Installed a .020 headgasket and had .010 shaved off the head. I put timing back to stock and it smokes white and hazes until it gets up to temp. Turbo spools real fast and pulls hard down low but after 2500 rpm seems to be extremely dead. From a dead stop it barely breaks the tires loose and it can't carry it for long. How much base timing do the non I/C have stock. Like 14 degrees??? Might bump it a 1/8 inch or more.
