Hey guys,
I have a 180sx with a RB20DET in it Mines ECU, Cooler and a zorst.
When i got the car i used to feel it pull hard when i put my foot down, now days i do and i dont even get that pull feeling.
I have checked out for any boost leaks and there is none.
Im thinking it could be coil packs or spark plugs?
Any thoughts?
