it doesnt have as much to do with your clutch as it does with your gas, you have 93 octane gas? if so thats what my psi is set at.


btw you still might want to look for a clutch sooner or later

Hi, I have Buschur cat less stage 1 plus fuel pump upgrade and I am runing 92 octane. I have my boost set at 21psi., so you think I could go higher with such octane? How much and how many hp do you think I will gain?
Thanks

Run it as high as you can with no knock...I'm in the process of getting my car tuned as we speak and I've been told that 22-23 is doable on 91 craptane with a good tune. We'll see.

Exactly, it is all in the tune.

If you are not tuned to run 24psi don't.

If you want to run 24 psi, set it there record some logs and send that into your tuner to get your map adjusted.

Hope that helps.
