When do u know u need race fuel...
Alright so im about to be tunning imburnes and my vitara setups for hoping around 20psi on pump gas 91 octane if possible? So what im asking is... To achieve this how do i know when race fuel (something over 91 octane) is a must?? I mean with just street tunning...?? I can keep the timming really really conservative and keep the afr's at low 12s to high 11s.. But how do i know when i need to take it up a notch and pump gas is not gonna work even if im not hearing detonation i dont want to get it to that point.

thanks bro! But how would i read my torque curve if im not on a dyno?? I want to do a good street tune for pump gas before we get it on a dyno and try bumping up the boost more for race gas. What would i look for with the plugs??

Shame it wasn't made a sticky, it had alot of necessary info on the dark art of plug reading.

Simple answer your boosting 20 psi+ race gas. I know I know you saw on the internet blah blah blah. Race gas is nice it allows huge errors in tuning. Play it safe and Im sure your not going to be running 20 psi on the streets no point. 25 degrees race gas lots of boost things dont break. Pump gas no timing in the motor things break.
