since i dropped comression to 9:1 from stock gsr compression i noticed at the same boost level that i was tuned at on stock comression that it is a tad bit slower lol. now i knew that this was going happen, but at first it felt the same i coudlnt even tell i lowered comression but now after boosting for about a week i can tell theres a big difference. i was just curious if there was a way to determin how much power i lost going from 326 @ 12 psi on stock compression----> 9:1 compression @ 12 psi.
