Got every thing needed to get my car (02 sti) to around 320bhp. Would i need to get it rempaped or could i use a decent boost controler?
cheers

 

Got to be a remap to be safe,A boost controller wont alter the fueling/timing as needed

 

Why bother even attempting?

Perhaps with the correct monitoring in place and a way of controlling fuel you may get away with something producing the peak numbers, but it'd be nowhere near the performance of a remapped STi in the real world.

A custom remap to suit your car and mods can be had for a just a little more than a decent boost controller............

As above, Ecutek and a few exhaust decat bits - bob's yer Auntie.

 

I doubt very much if even with the right bits you could get to 320 without a remap, I think the overboost fuel cut will be chiming in before that!
