For some reason i am only getting 11 psi with a 2.7 pulley. but when i reflash my car i get 15 psi but goes away once my car relearns itself...so im asking if anybody could help me figure out what i might have enabled that is causing me to be stuck at 11 psi.
i did the change from 180/140 to 255/210 and the problem is still the same... Any other ideas or was there more to it that just that simple change? Thanks for the reply btw
