Hi guys i need a little help i brought a s2 rst 3 weeks ago it looked like a chavs car and didnt run very well, i sorted the chav part out and took it to pj motorsport to have it set up, as soon as i had done that i started to have problems, every now and then when driving along the car will cut out and then when you start it again it will just keep cutting out unless my foot is flat to the floor, even when my foot is flat to the floor there is no responce at all the boost sticks at 0 and the revs are very low also while doing this there is alot of smoke out the exhaust, after a while of trying it will clear its throat and kick back into life anyone got any ideas. fuel relay is brand new as well as well as the earth.
