yeh as geo said 1 bar on a ct9 is quick enough do all the things i put in my earlier list first though cause if not your car wont be fuelling, cooling or have good spark. plus it will be hitting fuel cut all the time. do all them first then up the boost to 1bar then maybe after that 1.2 bar on a hybrid lol that should be more than enough power to cream a lot of things on the road lol
