GT PRO Performance Tuning announces the arrival of it's new turbo upgrade for the 335i

With our years of experience building forced induction vehicles, has lead us to this upgrade. Tapping on our experience in the way of utilizing the stock housings as we have done so many times successfully in the past, we were able to achieve what some say was impossible. A turbo upgrade that is virtually undetectable by the dealership. Those who are afraid of having issues at the dealership, worry not!! Our turbo upgrade cannot be detected, unless completely disassembled.

The proprietary GT Series compressor wheels have been specifically designed with the latest in aerodynamic compressor technology, we also keep the proper exducer to diffuser area for optimum efficiency. The turbine side has been specifically clipped to reduce backpressure which rounds out the upgrade.

Our dyno testing has shown a very nice 45rwhp gain at lower and safer boost settings.

The goal was clear, develop a turbo upgrade for an already outstanding car, and transform it into a phenomenal car. That goal has been achieved.

Additional tuning IS needed to take full advantage of our turbo upgrade, inquire with us for details.
