hey!
04 s2k @ 7 psi 293whp
I want to get it re-tuned to about 13- 14psi, so i dropped it off yesturday and he was saying he wants to tune it on race fuel.. so my ? is that if he tunes my car on 101 octane at 14psi does that mean I can not run pump gas( 93) or its not going to run correctly because its tuned on race fuel? sorry if its iin wrong forum and for the weird ?.
thanks alot!

 

If its tuned on 101 race fuel that is all you are going to want to run it on or you are asking for problems. You can run pump gas 93oct up around that range in boost anyway on stock motor.

 

I would go as high as you can on 93 and stay away from the race gas. That is unless you want to run race gas all the time.

 

play it really safe Tune it on 91 and put 93 in the car

 

hey guys thanks for the input:
he is gonna tune it on 93 octan..@ 14psi
appreciate the help...
