I have a buddy of mine with an LS2 GTO who's having some problems trying to tune it. He's running around a 11.5:1 CR an he's trying to tune it to run on pump gas. My question is, is this possible? I like to think you can only get so much out of 92 octane before you run into detonation problems. what do you guys think?

 

it can be tuned just fine, theres lots of people running much more then 11.5 on 92 octane, just needs a good tune
