The stage 1 ECU and stage 2 TCU have turned my b9 RS5 into a totally different beast! I honestly didn’t think it can shift faster but holy cow was I wrong. The punch from 1st to 2nd is insane. I’ve only been able to do one 0-60 launch so far, screeches the tires from 1st to second. And the sound from the intake is amazing! I find myself revving it up just to hear the intake and the new exhaust sounds! Will definitely be staying with 034 for any of my aftermarket upgrades! Also, Turbo, the AI assistant was a major help

Shipped quickly and a quality product.

Amazing service again. This is my 3rd tune purchase.

Fast shipping and fast response. Definitely satisfied with the upgrade.

I would like to express my appreciation for your products. This week I installed a Stage 1 tune on my SQ5 and it beat all of my expectations. For starters it only took about 15 minuets to install the ECU and TCU tune combined even though it’s the first time this car is tuned to my knowledge. The power is amazing and consistent. I wish I could talk to the 034 Motorsport CEO myself to share my gratitude and and how thankful I am for this. It’s easy, quick and amazing and I WILL buy from you guys again. Thank you.

Perfeito

Perfect

Great part, all upgraded audi needs one

Service was great

high quality parts

Just perfect!

The tune for my Q7 was perfect. Feels like it should come from the factory tuned this way. Great work!

Love the catch can, it does its job. I only have 16,000 miles on this 2023 S4 and when I took the hose off the inlet turbo there was already oil piled up right there. So I recommend a catch can for these cars. . and I change my oil every 3000 miles.

Great site and fast shipping
