no what i meant was after almost going a year of nitrous use he hit the button trying to catch up with the M3 and bang it just died. but yea you already stated that he was using it when it broke down.Actually he went almost a year of nitrous use, started with a 50 shot and moved on up from there to I believe a 150 shot. He was trying to keep up with a stock M3 and thats when it happened. He is sure that the valves has started wearing and the pistons had been scrubbing the walls for a while. Luckily he owns a shop so labor is free for him.
