ls1 missing at high rpms help?
ls1 missing at high rpms help? i have a 98 ls1 with a 10 psi vortech system aftercooled and 42 # injecters. ok now this is whats going on any were above 3000 rpms it will start to cut out it will like change every time like 3500 or 4000? but if i keep the gas to the floor it will start missing and spitting. if feels like i loose the boost but my boost gauge stays up? any help?
First off I would stop trying to go rev thru it. Your going to mess something up. Do you have a tune on the car or what vortech gave you? What is your fuel pressure? Do you have a wideband on the car? Have you checked the plugs? What kind of plug are you running? Need to post a little more bro for any of us to help you out
