Love it, its feels like when Gohan from DBZ finally unlocked his potential in the Majin Buu arc.

Everything was as expected.

Amazing service, 10/10

Fast shipping.

I have been doing my most best to show everyone around me how good of a brand 034 is such as making content and more, looking forward to possibly gaining a relationship with you guys to keep permotinh the amazing parts you sell! Follow my instagram or TikTok to see my advertising at Treet. tegart on all platforms!! Thank you 034!!

Super easy and helpful.

Nice job

The springs look great on the car, but wow they are noisy

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!

Bin sehr zufrieden!! Die Lieferung erfolgte einschl. Verzollung innerhalb von 3Tagen. Auch die Nachlieferung erfolgte im angegebenen Zeitraum. Abwicklung nur über Kreditkarte und Kontakt nur mittels "KI" - ohne Probleme. Übersichtliches Kundenkonto. Qualität der gelieferten Ware augenscheinlich sehr gut. Noch nicht getestet! Sehr empfehlenswert, da die Lager sonst nirgendwo mehr erhältlich sind. Jederzeit gerne wieder. I am very satisfied!! The delivery, including customs clearance, took place within 3 days. The subsequent delivery also occurred within the specified period. Processing was only via credit card and contact only through "AI" - no problems. Clear customer account. The quality of the delivered goods appears to be very good. Not tested yet! Highly recommended, as the stocks are no longer available anywhere else. Would gladly order again anytime. Juergen

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
