I just bought a ZEX EFI kit and im wondering if I in fact need a tune for it. im going to be running a 75 shot.
current mods:
2.59 vmp pulley
JLT Carbon fiber intake
2008 lower pulley
VMP 91 octane tune.
Im going to be changing out spark plugs with NGK TR6's.
I just need some input on this because I know with a 75 shot you dont need to change any timing at all so what has to change in order for the motor able to take this shot? Ive also heard that it is bad to run gas through the supercharger is that also true? Also talked to Evolution told me i needed to up the octane but the highest is goes where i live at the pump is 93 octane.
Appreciate the input ahead of time
