I just installed an Exhaust system, a suction kit, a single plate clutch and a blow off valve, and as soon as i got the car ready, i took it for a run, when i remove my foot of the clutch and gas OR go on high Rev and then press the clutch without gas the rev goes down and the cars engine turns off (even on speed of (60kph) does anyone here know why this happens?
some people say its from the blow off valve and its somthing normal, i dont think this would happen to a lightly modded car

I think you might have to adjust the blow off valve. Its normal for it to do this, I had the same problem. There is a screw that is used for adjustment.

Its normal..either adjust it like Gicho said or get an uprated spring..
