We Are Tuning A 01 Z06 Vette With A Custom Op (202003) and are having a little issue. The Car Is a fully built 382 LS6 with a F1-C Procharger making about 15 psi. Between 170-180 kpa I lose timing, 3 degrees at first and then about 1 1/2 after that. I have checked TQ mangment, enabled forced octane scaler, all air temp and coolant temp modifiers and everything else I could think of. What am I missing? Can I log some pids to figure it out?
P.S On a side note when changing to a custom os on a car with a auto trans and no maf how does the trans know when to shift ?
Thanks, Bill
