Hey I have a 13 fost, full bolt on , solid motor mounts & stratified crackle tune, stock bov. let’s start off with my car has a slight exhaust leak this might be major but I’m trying to make sure, I usually hit peak boost at around 22-23psi in 3rd & up, now recently I noticed I’m peaking right around 18psi & I feel a little lack in power.. I did a compression test & it’s 162 in all cylinders.. my plugs are gapped to 0.025 (recommended by stratified) so i have no idea what’s going on , any ideas ? Opinions? Thanks.
