Roughly how much hp would I gain by switching from a 93 tune to a c16 tune with only messing with the timing and jets in the carb, keeping boost the same? Im running a procharged 393 running 11 lbs making 564/563 off a very basic tune to break my clutch in, goal is 750 and I want to know how much of a gain race gas will give me before uping the boost. Sorry if I sound like a newb, new to forced induction so Im learning about boost in relation to timing in relation to gas octane and all that
