S6 C7.5 APR GIAC REVO Unitronic but which one?

[pez81]

I just prefer my S6 which is due to arrive 1st March. I plan on getting a tune after the engine has broken in, and having spent countless hours reading all the posts for each tuner I can't make my mind up. APR have overall the majority of people running their stage 1 and great times and big numbers. Unitronic have the fastest quarter mile and opportunity to tune from home. In based on the UK so that's quite good for me. Revo don't seem to have said much and their site is out of date and doesn't have the c7.5 yet apparently that's coming out in a few weeks. I nearly went GIAC on my S4 but dodnt as I bought the S6. Again not many people seem to have GIAC on their S6 not sure why?
So what the fudge am I on about anyways? I want to know are APR that much better and are their dyno figures that accurate. They posted 480hp stock but no one else has come that close so I can only guess their dyno is reading a bit higher. I may be totally wrong.
Has anyone driven more than one companies tune for the S6 and how did they compare? Id really appreciate anyone who can chip in on how thfor car drives or performs in the real world to help me make this decision. If you have any base dyno and after readout that would be great. I'm terrible if I have more than 1 choice for anything I over think and spend too long wondering what to get. Are they all pretty much the same?

Thanks in advance and happy New year to you all.

Majority will say Apr as they have market share a few will say unitronic myself is included in that, even less will say giac and no revo supporters in here so you won't hear from them.

I would try and meet up with people who have tuned cars and see if they will let you go for a spin and see what you like.

I think the quarter mile time is the best indication of the straight line power, and I can personally vouch for the driveability of the car, with the Unitronic's tune. I have checked with VCDS and it hasn't produced any fault codes.

But for me the key thing is the ability to flash back to stock myself, not just for services, but if you think the tune is causing an issue, you can flash back to stock and see if it's still the same. This will also apply to the TCU tune, when it becomes available.

I went with APR - I was one of the "early" adopters for the C7.5 I guess and there were some minor issues with car going into limp mode. APR fixed the issue and I haven't had any problems since. It is a night and day difference with the tune.

Thanks Sciblades for the reply. Not many S6s in my woods and fewer tuned 4.0t unfortunately. I'm going to have to do this blind. I see you ran an 11.3 what was that with? Impressive. Is the torque lower with unitronic? I spoke to the owner he seems nice and I like the idea of the one at home. No revo love? I won't ask.

Thanks buddy yeah I like that idea too. Do unitronic update with newer additons of the stage 1/1+? Like APR do?

[sciblades]

Uni runs 11.4@121 on 94oct stock everything else not bad for just a tune, the 11.3 run was beta testing the rs6 turbos it has run much faster but uni hasn't released that software yet. Of course every tuner updates their files when they can make more power.

Hi mate is the new 1.1 that much better have you got the tcu tune too?

11.4 is fast. And that's without turbo back or tcu it seems they are doing something pretty special over there.

[whiteq]

I'm on REVO and very happy with it, I'm in Australia and it is significantly cheaper than APR here. No complaints, the car is a monster

[Soft]

Have you found a way to get Unitronic in the UK, Im in Norway and cannot find any close dealers.

[Sean@APR]

APR have overall the majority of people running their stage 1 and great times and big numbers. Unitronic have the fastest quarter mile and opportunity to tune from home.

Just a minor clarification, we actually have the fastest. Ours was done on race gas, but in much warmer conditions. If somebody takes our pump gas file out in similar weather to what that 11.4 was done in, I'm quite confident we'd do well.

As for what tuner to chose, I'll say the same thing I always do:

Don't choose a tuner, chose a dealer. Go to the dealers, talk to them and get to know them. You're talking about modifying a quite expensive car and you'll eventually need support for something. Having a local voice to call on that you trust makes all the difference when you need something.

This - I went with GIAC ECU/TCU tunes on my S6 because that's what my shop sells, and they've given me great support. I know I have somewhere to go that I trust if I need some assistance.

I Couldn't have said it better Myself, Sean. I will also take it one step further because it is a chain of support. The manufacturer supporting said dealers seamlessly creates the greatest overall experience for the consumer, which is what we we work so hard to achieve. This is why we choose to sell APR and proudly represent, supply and support Connecticut and the surrounding states north all the way to Maine.

If anyone has any APR questions, feel free to shoot me a PM, a phone call or and e-mail.

No TCU tune, only the 1.1. Yes, it is much better because the car doesn't go into limp mode.

Are you in Newcastle, NSW?

I think you mean quickest, the 11.39 run you are talking about actually had quite a low trap 119 if I'm not mistaken

You are the fastest, you're right and we've got the quickest.

We need to beat on tude to update that thread.. or start a new one.

Edit: Nevermind, I found your slips in the thread, but we still need a properly updated list.. makes it much easier.

They do a remote tune from home

[pez81]

Thanks to everyone for commenting so far. I think it's Unitronic or APR for me my local APR dealer revolution 247 are great guys too. Price wise what we talking in the UK? Any discounts?

[ImpartialFocus]

I've got a REVO on my 2014 S6. The local shop I use supports it. I think the APR can get you into a bit more trouble if you don't pay attention to specifics, REVO seemed a bit more 'safer' for us modest types. It makes a difference no matter what company you use!

[whiteq]

Agreed, the car is so brutally quick I don't think it would make a huge difference which tune you use. I had REVO reverted to stock as well before a dealer service and it was not picked up as TD1 which I am very happy with. I would personally go to who will support you. FWIW, I have tuned approx 5 cars with REVO at different stages of tune and not had a problem with any of them.

Hi thanks for the reply. Revo is yet to release the c7.5 but apparently out in a few weeks will be interesting to see what they deliver. Have you done any tuned runs or know what it gained on a dyno?

That's what I thought. I can't imagine there's much in it either. I don't have a lot of choice in dealers here local company I mentioned is APR and the other place which is Revo has some worrying reviews

I don't know the pricing, but I do know there's a sale going in the UK now on APR stuff. :) Give your local dealer a call, they're the only ones that can give you exact price.

For the US people reading the thread and confused by that:

The UK has laws prohibiting companies from setting retail pricing. We can set a "suggested" retail price, but the actual price the customer pays in the UK is set by their local retailer.

We are all about the haggling. ;-) my dealer said Sean should just email me the file for free. And send $500 too

I haven't, but want to. Here at altitude (I live about 6000 ft), I was seeing 0-60 times around 3.4 to 3.5 seconds. The Revo tune made the car perform better with the Turbos considering we have less air. The Supercharger (on the A6) is superior off the line here in Colorado, but lacks on the high end. The stock S6 Turbos did okay, but lagged for stoplight drag races. The Revo tune has a slightly better curve in the lower end HP that I liked. I would've tried APR if my local shop would support that one.

[VVG]

I have always used APR tunes on my Audis for the last 17 years. Here's why.....

Customer and dealer support. When tuning a car, most reputable tuners will be able to get you decent performing software. But the customer/dealer support network is a different matter. APR not only has a solid product but they are well supported, so there is never an issue if something needs to be fixed, upgraded, etc. Love my APR mobile too !!

A 1/10 of a second here and there really isn't a deal breaker for most people who own these cars. If you are seriously into drag racing, a big premium luxury car isn't exactly the best platform to start from, anyway.

[siberianwolf]

I'm running Revo on mine, no issues at all with the tune. Great support from local dealer and Kevin from Revo

Initially wanted to go with APR but due to awful local dealer I went to Revo... recently got the info that local APR dealer is now able to do 4.0TFSI tune but full price + no test period

GIAC/Unitronic are not available at all here

You just sold me well done. Youre right in every point you made thanks

Hey APR....where's my commission? !!

Hey APR....where's my commission? !!

Come meet me at the bar after waterfest.. I've got the first round

I'll be getting tcu too so make it an extra large one. Thanks to everyone who contributed to this thread. I never thought about the dealer service side of things and service is really worth paying extra for. I'll be doing some videos too eventually and get down to drag strip. The weather is always cold here and at sea level so should see some impressive times. Thanks again you're a nice bunch

I'll probably be back in the UK in the first few months of the year. I'll ping you when I'm there and we can hit the pub for a few.

Haha yeah but the UK isn't a puddle depends where you're gonna be. Come up north I'll take you round Newcastle.

I have an APR tune in my 2013 S7. It's way faster, but I wouldn't do it again. Audi voided my warranty when they found it and I had several issues with the coolant lines bursting twice (technicians say the tune makes it run hotter) and the turbo relief valve breaking (a $3500 repair).

It's plenty fast stock and the parts simply can't take the extra HP. The S8 uses the 8 speed torque converter transmission because the extra HP in the S8 causes problem on the dual clutch 7 speed. The APR upgrade boosts power close to S8 levels. I turned my chip off because I was afraid the transmission would be the next weak link in the chain.

Needless to say, I won't be buying another S car. Definitely going M or AMG.

Also, I went 11.98 at 116mph at Auto Club Speedway in Fontana, CA. Significantly slower than the times they show on their website, but still pretty good for a 4400 pound street car.

Interesting post. That's the first issue I've heard, his car might have just had issues from the factory or a poor install on something. I think it's the risk you other take or don't tune. Obviously if it all goes wrong you'll be crying that you shouldn't have tuned it but how many cars have been tuned and by APR recently that have had any real issues? It would be interesting to hear if there are any more. You could always go for something like MTM or a tuning box. You pay quite a bit for MTM but it covers you a bit i believe as its just a piggy back.

Fuck it! Mine is going to APR when i get it. I can only blame myself if it goes tits up.

This is another one of those cultural differences. I was in Manchester last month and needed to have a meeting in Scotland. I went to the office in the morning, had a coffee and said I was taking off for Scotland, be back in the evening.

They all looked at me like I was crazy.

In the US, we think nothing at all of a 4 hour drive. In the UK, that takes you halfway across it.

Haha! yeah that is funny. I live in Newcastle and it takes 2 hours at least to get to Edinburgh on a good day. The other one is hey you're from London do you know John? That happened in Vegas? I said to the dude bro there's 65 million people on my tiny island. He didn't get it.
