I am putting an iron 6.0 liter in a c5 right now. The car is a stock longblock ls1, stock cam with intake, tb, longtubes, and meth with a 2bar SD tune.
If I leave everything alone in the tune, can I just start by dialing in the VE again? Does the lower compression bring me farther from detonation, or will the increased airflow from the added displacement bring me close to the edge?
Should I just start from scratch, or can I leave this tune mostly intact and adjust ve?
Thanks,
Jack
