Excellent communication and quick response time to my questions. Very satisfied, I have my Q8 3. 0T tune and my 2019 TTS both tune by 034

So far stage one has really woken this engine up paired with the super duke intake bundle, street density transmission mount, and transmission insert. I bought the stage two + package because I eventually will be running stage two with the hpfp upgrade. But as of now stage one ecu and the stage two tcu tune have been amazing. Stage two tcu is a whole new beast with amax shifting. I actually have amax off for when I’m just pulling around town because I like the zf8 farts. Waiting on my Intercooler to flash stage two then I’ll start taking the car to the 1/8th mile track I have close by and hopefully be a good race against all the bmw guys out here.

I had an issue with the acceptance thru Fedex, Rob from 034 answered correct and helpfully, thanks

Great company, shipping, communication, etc. worked with me to rectify the dissatisfaction of the product, will certainly buy from again in the future.

Always easy to order from. Quality products as well!

Amazing tune

Fast shipping excellent customee service, the flashing tool is very easy to work with, the tuning is perfect on ny ausi s5 b8. 5

Quick shipping. Great fitment. Nice design. Perfect sound.

Thank you, I recommend!

Amazing, seeing the exact horsepower as advertised which was surprising as well, the car even made slightly higher, although it was short lived as my alternator died (completely unrelated)

Great kit. Came as advertised

Came pretty fast

Came quick! Ignore my rusty pulley.

Really enjoying the new plugs! Car runs fantastic!

Easy install, look OEM, and most importantly, they actually work. As a bonus, they drastically cut down any wind noise when the windows are up, not just down.

Dropped in perfectly. Minor rool mark on the underside of rail billet piece. Utterly cosmetic and even hidden when installed. Deal.

Great the Pcv hose was collapsing originaly but whenninused your hose setup it did. not problem solved. Fast shipping quality parts Thank you

I had a failed OEM PCV Breather Hose causing my pcv to fail so I bought the 034 as a replacement, the install was easy and straightforward however my engine cover doesn't fit around the oil fill cap. Great Product definitely recommend for preventative maintenance.

Another great 034 addition to my RS!!
