Gday, im new to this site and to the fg xr6t world. I currently have an fg 2012 mk2 xr6t sedan running 14 psi with simple mods such as 3 1/2 dump n high flow cat, upgrade cooler n piping, battery relocation kit w 4" intake, tune, making roughly 280rwkw. Want to get to the 350 mark with added mods such as 400lph fuel pump, 1000cc injectors, twin 2 1/12 cat bak, 12psi actuaor, valve springs n oil feed line. I understand that stock turbos run outa puff round the 350 mark, however, my tuner/mechanic told me with the added mods im only looking at the 320 mark TOPS!! is my 350 mark realisitic with such mods?? Any advice will be greatly appreciated. Cheers folks ?
