Just a sanity check befor we start to dive in to the motor, Car is a 02 Z06 416 LS3 9.1 comp,6.0 truck heads, small cam, Kooks 1 7/8, P1-SC... We are having a problem with the ignition wanting to to break up(we think) at 5,000 rpm, allways at 5,000. We have changed the blower pully so we are only making 3psi so its not boost related, we pulled timing ,added timing,changed spark plugs( TR6 With .035 gap) changed coils, changed the CPS. So now we are at the point of thinking its something with the file or its something with the motor. If some could please look over the file and just make sure that we are not over looking something.
Thanks Bill
