Revo Stage 1

[BoBsMiTh]

A friend of mine is going to get his A4 tuned with Revo Stage 1 for $500. They told him that it would increase performance and gas mileage. Im thinking about doing it as well but Is there a down side to this? He has a 2004 A4 and was told it would take it from 180HP to around 230ish, how true is that?

I just don't want to do anything that will kill my engine. Im afraid its like throwing in a turbo or supercharger in an engine that can't handle it and just destroy the life of the engine.

any info would be greatly appreciated, i am completely ignorant about Revo.

Thank you.

Yup, the chip will do all that it claims in terms of hp, torque, and gas mileage while putting very little extra strain on any of the engine components (except the dv, which you may want to upgrade). The only reason some people are weary of the chip is that it voids warranty (but I don't think you'll have to worry about that).

I'm not sure what claims regarding mileage they're giving, but unless you're driving really gently you probably won't see a significant increase. On the other hand, driving moderately aggressively won't give you a big decrease, either! But if you drive hard you'll see a definite decrease.

what is "the dv"?

It will void the warranty eh, even if i get it done at a VW/Audi dealer? I have 5000km left on my warranty so i don't want it void until its through! I just bought the car and anything that remotly seems off I'm having changed, i.e. window witch, review mirror (its the auto dimming one), engine cover,...etc.

well, more power = less power to get to a desired speed, which means keeping it in lower rpms, which would save gas.

correct me if im wrong.

It does add more stress because you are requesting boost, timing that a stock car doesn't require. To this date, I have not read anyone blowing, damaging your engine or tranny from only a chip. The worst case is your dv blowing and you can prevent this with an aftermarket dv.

I haven't had any problems with my Revo, but I do get ok gas mileage, not good compared to others.

A little heads up. This forum is for the 2005.5-2008 A4. You might want to post your question in the B6 forum considering you're discussing a 2004 A4.

Or, you might want to do a search and find that your question has already been asked and answered multiple times.

[muffinman]

it's true.

just do it - you won't regret it.

Yup, I think that's kind of the premise. However most people probably don't increase their gas mileage because with the chip you seem to get a little heavy footed.

DV is short for Diverter Valve. It's usually recommended you upgrade the stock one once you are chipped because they are notorious for blowing after the increase in power.

Not many dealerships offer chips, but if yours does then your are correct, it will not void your warranty however you will be paying extra for it (usually about twice the price of a regular dealer).

A chip will void your warranty, but only if your dealer knows about it. The companies that sell the chip (i.e. apr, revo, giac) give you the ability to "hide" the chip. Lots of people turn their car back to "stock" mode when they take their car to the dealership for whatever reason and for the most part the dealership won't be able to tell your car is chipped. To have the ability to switch your car between stock and chipped it'll cost about $150 I believe.

Well, it will take the same amount of power, but less percentage of your total power. The chip increases mass air flow, so more gasoline can be burned, which gives it the extra power.

But maybe tuning also adjusts the fuel/air ratio to run leaner in some situations, which could increase mileage.

Just speaking from my own experience, though, I have not seen a discernible increase in mileage.

Thanks for the "Heads up!". I have a 2006 A4, my friend has an 04 A4 that he is putting the chip in! I did not think that background was relevant to the discussion. If i have known that the "Audizine Organizer" was going to hit my thread i would have put it in!

Here's a little heads up for you, if you don't have any information on a topic that is being discussed or a link to another thread that does, don't waste peoples time with a useless post on how to post! I think we all know how these forums work!

Cheers!

Most of you guys are awesome and have great info. I've been on a few other boards and this by far is the best with knowledgeable people that are more than happy to share. Not dicks that just flame ever chance they get!

Cheers!

REVO stage 1 won't hurt your turbo or anything. You might have to replace your DV or PCV. the gains seem pretty accurate but you wont get better gas mileage

I got better gas mileage with my revo stage 1, when I went to stage 2, didnt change much. and im sure when i go to stage 2+ i wont gain ANY cause of the fuel requirements..

[AudiWxGuy]

You still are at the same RPMs in terms of speed. Your car still does 80 at 2600. You just get more power through the ppwerband.

[4ringsinLA]

your car with revo will destroy the b6's with revo...well any chip for that matter. also, I don't think that your friends car will hit 230ish hp unless he gets bigger injectors.

Im sorry, I would highly go against this comment. But think what you want.

[etnies]

im the friend thats getting it done hah, and its the flash not chip, but thanks for the dv upgrade

[Sanjman]

It's surprising to see how many people don't know how the chip software actually works... ... oh well to each his own.

[autoverruckt]

I got maybe 1mpg better but you have to look at it this way - most of the time adding power means you have to sacrifice fuel economy. With a flash you don't have to suffer a loss. However be warned that it is difficult to drive 'normal' as the the added boost makes your right foot have a mind of its own.

[BoBsMiTh]

what is the difference between a flash and the chip?

Care to explain?

[A4A4A4]

They're the same thing.

[back2chitown]

Care to explain?

from my understanding and from looking into the differences while researching this stuff for my previous car,

"Chipping"=there's a chip in your ECU that is actually removed and replaced.

"flash" means a computer is actually hooked up to your car via the OBD2 port and a new program is downloaded to your ecu.

First off, you never mention in your OP that you had a 2006. Every reference in your OP was to your friend's B6. I can't read your mind, and neither can other people. So, another heads up, if you want correct info in the future, it would benefit you to let people know specifically what you're wanting info on...your friend's B6 or your B7.

Secondly, every single question you have asked has been answered numerous times before, so in reality, the only person wasting people's time, is you.

Cheers!
