I talked to Upsolute Chip Tuning Company and they can upgrade the ECU on the cayenne for $500.00 plus $25.00 for shipping... The gains were approx. 40HP/torque.

I was wondering if anyone thinks this is safe, as no one I have heard of used them for the cayenne. Iknow people that use Upsolute and loved it, but I just dont know for cayennes. I was wondering because 525.00 would be a hellofalot cheaper that 2K plus from other companies?

 

Damn..... I was just about to say that $500 is a little bit 2 cheap compared to the rest. I think you should go with giac since they have a very good reputation. Plus u dont want to take any chances on luxury car.

 

thanks for your input. I have heard nothing but good things about GIAC.
