The RennTech tuning module allows the user to change the performance level and gives the ability to set different performance levels running both higher or lower boost compared to delivered settings. This gives you power on demand or economy when you want with smooth torque delivery and performance throughout the entire powerband. This also allows the user to compensate for fuel quality and places of extreme climate or to adjust for higher octane fuels and the added performance of racing blends.

The lightweight forged billet wheel features a dramatically larger than stock impeller (inlet side) and an increase in the turbine trim (exhaust side). This combination of high quality, lightweight components coupled with less rolling resistance compensates for turbo lag despite being a functionally larger turbo. Our Turbo Upgrade uses a modified bearing and a stronger shaft, to remedy the factory's weaknesses. The end result is nothing short of spectacular with the RennTech turbo package making up to an incredible 460 HP and 415 TQ at the crank.

More power isn’t the only performance benefit as our turbo spools quicker, offer a more responsive throttle and immediate power delivery thanks to a reduction in exhaust back pressure, rolling resistance, higher RPM's and a lighter rotating mass. In addition, our turbo upgrade kit includes the RENNtech ECU Upgrade and high-performance air filter. The Turbo Upgrade has been developed in partnership with RennTech GmbH, facility in Germany, and was tested and perfected on the Nürbugring. All parts are tested in-house as well to ensure years of 100% trouble-free and leak proof operation.


To reach the maximum power level, RennTech downpipe is required
This Turbo Upgrade requires an additional core charge, which will be credited upon return of OEM turbo core to RennTech 
We typically see slightly higher baseline numbers than claimed by the factory. Numbers will be dependent on conditions and fuel quality

                                          Some items may be special order specifically for the customer’s vehicle. These items generally require a deposit or paid in full.

Cancellations are not allowed on special order parts.

We will absorb these fees if we do not have the item in stock OR if you agree to the original ETA and that ETA is NOT met.
