Hopefully I feel the same, I ordered it yesterday along with a xcal2 and JLT CAI, kind of wondering how much rwhp I will loosen up with these mods. I am not expecting much but does anynone know actual numbers? or a guess? Will the difference be enough to show at the track or do I need more mods to start seeing a difference?I feel like I felt a difference with mine installed. I know it's always psychological but when I put mine in the car felt a little more responsive all around.
