We might as well round out the performance upgrade subject with a discussion on chips as well as air intake and exhaust systems. Has anyone added a performance chip or reprogrammed the factory computer?

I read what Butch wrote about the Power Programmer. But was told by 2 different shops (and called the company myself, they said wasn't necessary) that changing to the 180 degree Powerstat thermostat was not necessary. That they haven't found a difference in performance having it or not. I seem to have much more power at take off and freeway driving, every time I look down I'm doing 85 without much effort. Next thing I was thinking of doing was the K&N performance filter pack. ?Thanks for all the info.
