Hey guys, I just recently bought a fg xr6t ute mk11 came with east Coast customs tune ( 16psi ), sct flash tuner, venom high flow cat, 1000cc injectors, process west cooler and piping. I've just done a battery relocation and turbo side induction ( 4 inch pipe and pod ) I was just wondering whether or not I should be getting a retune with what I have done, to be perfectly honest I don't know to much behind the performance upgrades my mates have all had/have f6/xr6t so have been relying on them for there input. I'm hoping to achieve 300-320kw on 98
any advice would be appreciated cheers
