I know there are a lot of factors to this but I am trying to get a concensus as to what is safe. My car as it sits has 11.5 degrees in it and my tuner didn't want to add any more until I get my fuel situation fixed. Well I will have that taken car of and when I go back in a week or two I want to know what is the max. I was thinking 16 or 17 would be ok with 93 octane. My car is 9.5 to 1 and has a front mount intercooler. Right now its making 12lbs of boost and when I go back we are going to rev it a little higher to try and make 15lbs. My goal is 500 rwhp on their Mustang dyno. Right now its at 441.
