A friend of mine is wanting to fit a stage two cam I to his new edge. I don’t agree with this but he is anyway but now he is saying that a stage two cam will work fine with out a tune, is this correct? The only mods he has on the car are long tube headers. is he just wasting his money? He’s not after more power just the idle sound of a classic V8. So question is is he wasting his money? And if not will a stage two cam work ok without a tune ?
