    I plan on getting it when my warranty is about to expire.

    I'm on the same boat, just waiting for my warranty to expire. There's a local shop out here in Austin that reflashes for APR.

    So this is my 2nd attempt and resurrecting some old discussion and hopefully we can generate some new discussion and maybe even practical experience.

    So some things up front, I am an engineer (mechanical by education and nuclear by trade) and not a mechanic meaning that I understand how things work but any time I turn a wrench, I am just as likely to strip the bolt as tighten it. So while I am very interested in researching power mods, I am going to leave the wrench turning work to someone better than me. I also understand that any performance mod involves risk. I am fine with risk, but just want to understand and manage the risk as best I can.

    If possible, I would like to limit the discussion to APR and specifically stage2. I know their are other bolt-on options and maybe they should be considered. I also think stage1 seems fine, but it just seems like the jump to stage2 offers some real hardware backup to the software mod and seems to be the best bang for the buck (literally). I also think the jump to stage3 is another quantum leap in equipment, price, and performance that is beyond what most people want to do.

    Finally, I am not looking to build a race car and my S3 will remain my daily driver. I love the S3 and is sporty enough for me, but who would not want another ~100 hp and ftlb at what seems to be a reasonable price. I will never have my S3 on any track and have never driven any car over 120 mph and usually 90 mph is my max, but additional acceleration specifically between the 0-80 mph range is always nice. So maybe the stock S3 is enough, but at the same time maybe my semi-conservative drive style mitigates any ECU or other mod risk.

    So after a long preamble, here are the points I would like to discuss:

    - By my quick count (only based on www.goapr.com , I have not talked to an APR dealer yet) the stage2 APR mod that I think is most appropriate includes: high flow exhaust (reqd, $900), intercooler (not reqd, $900), intake (reqd, $450), and the ECU2 ($200). To be honest, I am not entirely sure about the price of the ECU mod so really need to talk to the APR dealer. It could be as much as $700 or might even be included with the exhaust pipe. Also I am not including the TCU clutch mod which is $600 since I think you can a get low torque version. I would be interested in people's opinion on the clutch mod. That brings the total to $2450 which is maybe a little more than I originally thought but is still not unreasonable for the gains.

    - Personally I feel much more comfortable making ECU mods with some hardware upgrades. Increasing intake flow, exhaust flow, and cooling are always sound engineering principles and I have done these simple mods without any ECU adjustments to other vehicles with good success. Any input on these specific mods would be appreciated.

    - I am less enthusiastic about clutch/transmission mods. One of the things I like most about the S3 is how crisply it shifts so I am reluctant to make any adjustments to the clutch or transmission. I have read APRs discussion of the TCU upgrade, but am unconvinced if it is necessary and am actually concerned it may incur more risk.

    - I am most interested in how the APR tunes will affect normal daily - with some occasional aggressive - driving. My primary desire is increased acceleration in a normal range not increased max speed and not necessarily always full throttle acceleration.

    - Next I think the S3 is otherwise well equipped to handle the jump to ~400 hp. I know many people would like to include major brake mods or perhaps traction/stability mods, but I think these would be unnecessary. My intention would be to increase hp alone with no additional braking/handling mods.

    - Finally, I think what would help most potential users is real world experience with mods (ideally APR specifically) so if anyone has experience or links to reviews of APR mods, they would be much appreciated.

    Thanks for reading and happy driving.

    @Brad_B

    I'd also like to see more tuning discussions. Last time I called my local APR dealer it was around $800 for the stage 1 tune, the guy said he'll discount if I purchased the down-pipe and exhaust at the same time.

    My dealer will do an APR tune for $1k that they say will boost output of my '16 S3 to 395+/- hp. They said some have complained that the Trans is less smooth once done but opine that the Trans learns and will adapt in short order?

    395hp? Are they quoting you a stage II tune?

    No clue but it's only a flash, no other parts.

    On APR's website their tune is quoted as making 357-381hp and Stage II producing 372-387hp with way more torque than Stage I.

    I didn't check it out further as you did. It's likely the dealer exaggerated slightly.
