Wow......I just got my car reflashed through the OBD-II port with the Revo Technik upgrade. Hitting 1.0 bars now and the power is amazing.

An added benefit is that the car actually runs much better now. It used to do some funny stuff when I was barely on the throttle in stop and go traffic. It was almost like the drive-by-wire throttle wasn't sure whether I wanted to coast or go. Its tough to describe. Anyways....its much better now. It revs smoother than it ever did. Much more driveable.

Did I mention its one fast Mother F-er now? Oh...and its friggin' fast now too. Like a whole new car. Did I mention its fast?

My mechanic is a Revo dealer/installer in Orange County. They're super nice, knowledgeable people too:

I'm also looking for some feedback with REVO program. Have you driven any TT with GIAC program? If you do, can you compare the power, smoothness or did you find any different between them? Thanks!!

 

I haven't driven the GIAC. I hear great things about it. I'm sure both are good. Hergesheimer can do a trial flash in your car if you're local.

 

I too would like to know how it compares to GIAC and PSI? Anyone have any experience? The claimed horsepower gains seems high compared to other ECU only upgrades.
