right just wondering if there is a point with a high comp engines where you hit a power limit because you have to lay on shit loads of retard to prevent detonation as the boost increases with engines around 9.5:1 compared to a low comp engine mapped with more advance at the same boost

its just im shure my zetec felt faster with the decomp plate on (7.7:1C/R)at the same boost compared to now with just focus rs gasket fitted at (9.5:1C/R) even though the car was remapped
