How many guys have a performance chip and have reprogramed their computer? I have 4.6 liter what kind of difference could i expect? Is it true that after you put the chip in you can only use high test fuel?

Just a couple of questions?

 

I just bought the superchip from Troyer and it is phenomenal. The increase in seat of the pants accelleration is great. You can run several programs but you will get the most response from the performance (91 octane) setting. It is well worth the money.
