Ok well i have an 06 rev up motor in my 03 g35, i have stilling exhaust from down pipes back CAI, stage 2 clutch ,merv and 5/8 spacer, im thinking of going to spray . 100 shot think ill have any problems with that shot? also im going to get tuned but dont know which management to buy.......

 

You'll probably want at least a UTEC. You should also check into fuel system requirements. I don't know if your stock injectors and fuel pressure is going to be safe on 100 shot.

 

What's a safe shot to spray on. Stock injectors and not touching fuel stuff?

 

You should be able to spray 75 shot and be safe.
