Got my stage 1+! Love it, can't wait to upgrade to K04 kit! Only waited 1 hour and they were done, got on it and 1st and 2nd gear pulled a lot harder than stock, smiling all the way home! Thanks Achtuning you guys are great!
No doubts. Best upgrade. Best shop

Got my stage 1+ done today. Went with 280cc Bosch injectors. Been driving on 91 mode for the past 4 hr's now. All different forms of traffic. Acceleration is amazing. 2nd gear is a complete beast and it leads into a monster 3rd... I swear it's an entirely different motor! Cant wait til the exhaust comes in for my avant... then it'll sound as good as it feels. ~~~

Just got my ECU upgrade today! All I can say is WOW, straight out of Achtuning I could tell a HUGE difference. The best "bang for your buck" by far. Achtuning has to be one of the best shops I've ever been to by far, not only were they nice they were honest and told me what I needed instead of what I wanted, I 100% recommend this shop to anyone and everyone.
Got my Stage1+ fully loaded program today, liking it so far!

Just wanted to thank you for the quick and amazing work you guys did on my Audi A4 this morning. I can't tell you how big my grin was on the way back to work! I can't wait to get back there for more future work. I'm super impressed at how fast and professional you guys are. Driving an automatic became fun again and I have you guys to thank for that. Keep up the awesome work!
