No, im running standard compression. I have 3 inch exhaust from turbo back, 3 inch highflow cat, custom front mount intercooler, Haltec coil pack, electronic boost control from the haltec ecu.. btw, everycar will react slighty different from similar mods. Your setup might max out at 240 - 250kw, where someone else may acheive 260 - 270kw... Will get you dyno sheet ASAP mate..
