So after awhile of trying to figure out why my gas mileage sucked ass after putting my skunk2 im on i emailed them and they told me, Well you should have gotten a ecu management..."Thanks for telling me this in the instructions, you listed cams, fuekl rail, fuel pressure gauge and thats about it you morons"...But anyways....I'm thinking of getting a Jet Chip I've always heard good things about them, but I was wondering if you guys had any input on these, the only reason i need the chip is to put the air/fuel ratio back into play and "unleash" the cars potential...thanks guys!
