*fixed so I could answer without offending the ghosts in the thread*

Close the exhaust cam earlier (trap some exhaust) and/or close the intake cam earlier (prevent full cylinder fill), but only at lowish loads. Reduces pumping loss a lot, holds on to more exhaust gasses which lowers the effective displacement of the engine, and maybe lowers emissions some. Watch your overlap so play with which cam changes work best, it's not the same for st cars and oem.


Now that all the hippy shinanigans is cleared up, great work on the car Ghost that powerband is great!
