APR Plus to Stage 1+ 93

[Mkai0]

Hello all, has anyone upgraded from an APR Stage 1 91 octane tune to an APR Stage 1+ 93 octane tune? Will the power difference be noticed much? APR’s page shows about a 50 whp difference, but I’m wondering if my inlet pipe, intake, and intercooler make most of that difference with my current tune. Not very confident with the answers APR tech support provided. They basically said “yes, it would be different” in their normal condescending manner, so any firsthand experience would be appreciated. I’m currently using the APR Plus warrantied tune, but want more power. Thanks

I was just looking at the same change! I think we would certainly feel 50hp/30tq....is it worth sacrificing the warranty we bought as part of the Plus is the bigger question. I may wait until I got 10,000 miles. Just over 3k now.

You guys know that I left APR for Uni after a very short time. I'll save the long story but just know that if things hadn't happened - I would still be on APR. What happened, happened and I switched, a little irritated at having ditched my warranty at that point but I figured if I wasn't staying with them, I might as well up the power. I went Uni Stage1+ ECU and stg2 TCU. It definitely feels a bit faster but I have to say.....if you are comfortable with APR and want that warranty - A friend (APR fan... ;) ) said something to me that made a lot of sense....after I had already went Uni, of course. You're probably talking .2-.3 difference on 93 between your warrantied tune and the 1+..is that worth ditching the warranty? I'd say if you don't want to throw a bunch of parts on it or if you just know you aren't going any further with it..stay where you are. If you plan to go even faster - then there is really only one option...bye bye warranty.

I’m at 2700 miles myself. I think Stage 1 93+ should be fairly reliable, just want to know if the bolton parts are making a large part of that difference.

My gut feeling says they are.. coming from the guy who decided he'll wait until his warranty expires to tune, but has done nearly everything else to the car minus the wheels, which are officially on order! Since I know people will be asking, APR intercooler, Eventuri intake, IE turbo inlet, Remus non-resonated exhaust are all my performance mods. MSS kit and 034 sway bar are my suspension mods, while the APR dog bone and APR DSG catch can are for the transmission. Couldn't tell you how much HP I have, but can certainly say the car is hella lot faster then stock!! So much so at 9k miles I upgraded my brake pads, which were still in good shape for more stopping power with Carbotech pads!!

Good to know thanks

Care to share your thoughts on the Remus exhaust?

Care to share your thoughts on the Remus exhaust?

This was my last performance mod and right away I felt it open things up for everything else! What others have said about this car being pretty restrictive due to the exhaust is true! I know most ended up going with the downpipe and having gone that route in the past I HATED IT!! Too loud IMO and the drone drove me nuts!! I sense most are happy with how loud it is, but heard many complaints about the rattling and drone. That's why I decided not to go that route as that would drive me nuts! The Remus non-resonated still adds a good punch to the car that you'll notice right off the bat, sounds AMAZING and pretty loud, but from watching other videos not quite as loud as a downpipe. However unlike the downpipe, I don't hear any rattling nor drone, which makes me as happy as can be. I know its one of the most if not most expensive exhausts for our car; however I think its worth every penny! I'd do it all over again and give it a 12 out of 10, lol..

I dont have an answer to your question but i would say your mods are def helping. With my experience with previous cars it is the “downpipe” with associated tune that made the big difference from my stage 1 stuff.

If i were you i would not exchange the warranty for the slight tune difference. If it were me i would Up the game when you are toward the end of your warranty and itll be more exciting., and a new experience. At that point warranty up i would just go straight stage 2. You are just power hungry right now (we’ve all been there).

I appreciate your logic. Honestly, my 2019 700 whp Camaro started to feel numb at times, however the way the RS3 lays down power makes driving more enjoyable. I’ll at least get the APR DSG update, lightweight battery, and midpipes for now.

So a buddy here locally had APR Plus and went and Dragy'd it... then swapped to 1+ and TCU 2 UNI... and has ZERO difference on 0-60 and 1/8 mile after 10 or so tries. It's impressive how strong the APR Plus tune is IMO.

Lol that’s me - working on duplicating the environment of my apr plus run. Da has gone up and I likely had less fuel for the original runs. Mph is increased - so there is certainly more power.

My first rs3 tune was with revo and after switching to uni I noticed that revo was a bit faster from 0-100km/h.
But when I finally tested 1/4 mile I was able to do a 11.0 sec run with uni where my best revo 1/4 mile was 11.3 sec.

I also read about some one going from CC to uni did see the same thing. CC was a bit faster in the beginning but at the end uni gave faster 1/4 mile runs.
Some mention that uni has a bit more safety built in when launching to avoid to much stress on the engine but once moving the tune really wakes up and you will see faster runs in the end.

Did you try a 1/4 mile run with your APR?

There was a video comparing these two posted some time ago but they both was running the 91 tune on 93 fuel if I remember correctly so your uni 1+ should in theory be faster :)

If you already paid for the APR Plus warranty expense, I would strongly recommend not to throw it out to move to the 1+ file. I have all of the parts required for APR 1+ (inlet, fmic, mids) and had the 1+ files loaded to my car after doing the inlet on my Stage 1 91-tune only ECU.

I was not happy with the 1+ files on 91 and E85 at all, and ended up having my shop put my car back on the 1 files. The 1 files have been consistent performers and allow me a little peace of mind that I'm not pushing the car to the limit all the time. And, I still got the car in the 10s on a real track, so I can deal with it.

That really helps a lot! I’ve been watching your build for awhile, and maybe I’ll do something similar down the road. Did get into the 10’s using 93 octane?

HAH well I feel stupid - didn't know you were one and the same lolol.

You're right on the trap, 60' got worse on Uni I saw, just a matter of tweaking that.

I'm confused as well. His 10 second time was on E85, which had to have been a 1+ file

10.96 was on the E85 file.

Hmm. So APR has files for higher octane on their stage 1 whereas Unitronic calls these stage 1+ files. You would think the terminology would be the same. So with APR they have a different file just because you have an intercooler and a turbo inlet.

APR 1 and 1+ both have 91, 93, 100, 104 and E85. The 1+ requires turbo inlet, intake and IC.

Anyone got a seat of the pants description/feeling between Plus and 1+? I’m heavily leaning toward just keeping Plus but the devil on my other shoulder keeps nudging...

Read some of cseaman’s posts. He mentioned the jump from Stage 1 tune to 1+ wouldn’t be significant.

However, Stage 1 E85 is a different story in terms of what one will feel. I have a strong feeling that with an inlet pipe and intake, one will only be 20whp away from a Stage 1+ tune. My current plan is to maintain my current APR Plus tune until at least 10-15k more miles, while moving to some lighter weight parts such as wheels, brakes, battery, etc
