I have a 98 EO SVT so no governor issues- The superchip has been a nice addition for me. They claim 5-10 over stock which I think is a bit generous. I like the performance of the chip in terms of overall drivabitity. My chip is burned to run well with basic intake and exhaust mods and that is where I really notice the difference. It seems to tie the mods together better, and does allow for better fuel mapping and secondary intake control. It does throw a cel on a regular basis though which can be annoying. It has never given me any problems though and does help the computer when you start throwing on intake and exhaust mods. I'm to the point now where any new mods will require the chip to be reburned.
