Do you raise fuel pressure w/ race gas?

[The Darkside]

I've never run race gas in my car,so I was just wondering if when going from "lets just say" 39 line off & 18lbs. boost w/ 93 gas to 110 race gas & 24 lbs.boost, should I also need to raise fuel pressure?

your chip should specify a baseline fuel pressure....start there...do not raise your boost from 18 to 24 in one whack....do it about a pound at a time and check your scan tool for knock, 02's, egt, whatever....this is called "tuning"

you may ultimately raise your fuel pressure for max performance.....

oh, your chip should match whatever octane you are running or you WILL have problems...do not use a 93 chip with 116 gas and expect it to run right

Probably not, but you will have to run it to know for sure. Did your chip maker give you instructions?
