MK6 GTI Pro Tune Sold Separately **$125 Non-Stock Turbo Tuning Fee Waived when purchasing turbo**
If you already have a tune with us, you can get a Top-Up Tune instead.
For above 350whp, we recommend fueling upgrades such as Stratified Aux Fuel and LPFP.
If you're thinking of upgrading from your stock turbo and want more than a K04, or if you already have a K04 and still feel as if it's not quite enough, our new offering might be just the turbo you've been waiting for.
Capable of over 500+whp, our turbo sizing provides considerably more flow and top-end power, while maintaining reponse, as you'll see in the dyno graph below.
This turbo features a ceramic coated exhaust side and a pre-installed, adjustable wastegate actuator. It also comes with a larger aluminum turbo outlet charge pipe (aftermarket intercooler required). An optional heat blanket can also be included to further minimize the amount of heat that radiates into the engine bay and improves spool.
