BrenTuning review
Hey everyone!
After about a year of owning my car I finally decided to modify my 08 335xi. I installed some VRSF goods. Downpipes, 7" FMIC, BMS DCI, Charge pipe w/hks bov. I brought it together with a Cobb AP running the stage 2+fmic map. I drove it like that for about a month and finally decided it was time for a ProTune. Bren had tuned my STI multiple times before with zero issues so he was my obvious choice. I gave him a call and setup an appointment for the tune. So this past Saturday was the day and I could not be happier with the results. Huge gains over stock and big gains over the cobb map. After all was said and done the car put down 379whp/409wtq. The power is smooth and pulls hard the entire RPM range. Bren also had someone meet me there to have the Alpina reflash done while I was there. Top notch customer service as always. I have always and will continue to recommend BrenTuning for all your tuning needs.
