18 degrees total as I recall. The tuner was surprised that's all he could put in and wondered if the motor might actually be higher comp than advertised.
The vette the motor was in before had a lot of different variables than I do. Including
cold air intake
Aftermarket TB
LS1 intake
Headers and different exhaust
Ran 50/50 91 octane and 100 octane (I think)
aggressive tune
432WHP in a C5
I have
hot air intake
ported truck tb
LS6 intake
stock manifolds and custom dual cat back
Run 91 octane with 1 quart of Torco
conservative tune
391WHP in a C3
