I'm thinkin about tuning it for that as well.. Do you have any issues with the extra boost and only running 91?? K/B's website recommends more octane for the higher boost and 91 for 5 psi.. I'm running 91 now..

 

do you not have 93 where you live? 93 is the standard "super/ultra/best" stuff around here... although on occasion ill see 94 at a few select places every once in a while.

 

I have had no problems with only running 91 but of course my car is tuned for it. you should be fine running 91 on 7psi if you get it tuned for it.

 

Paulstang thanks when I get the rest of my performance stuff on I will take it down to k/b and have them tune it for that.. They're right around the corner from me, literally lol.. and ardoller no we only have 91 in california, 87 89 and 91, at least southern cal I cant speak for northern cal..

 

NO problem anything else just let me know.
