I recently bought a 98 z28 with some bolt ons and a cam. The guy I bought the car from said they had street tuned it using "efi live". The car runs decent at WOT but anything less and it just spits and sputters. Is there anyway to reset the ecu to the stock settings? not sure what to do any help is appreciated.

it needs some O2 sensors. My truck did the same thing. You can test this by unhooking all of the O2's and go drive it. I drove and raced mine for a year before i bought new ones
