RE: C&L CAI
higher octanes have more power potential. depending what is available in your area, (91 is the highest for me here in socal), get the perf tune that matches the highest at your local pumps. dont expect noticeable differences between 87 vs 89 and 91 vs 93 even if there is a diff. 87 vs 91/93 is where you'll feel the diff. if it were me, i would purchase either the 91/93 perf tune from VMP or the 91/93 race tune from bama. nothing against other tuners, its just that i have experience with bama, which i'm VERY happy with and i've READ LOTS of compliments on VMP tunes.
