cheers for the reply's, my problems have been no end, first off the car sat for 2 month with no t&t and wouldn't run, i got it running and just couldn't get it perfect so i bit the bullet and paid £130 for rolling road tuner who got the car started then 2 mins into getting it going he fiddled and i came away with a car that wouldn't start at all and £130 down, so i went away ready to break the car but im very persistant and didn't give up, eventualy i got her running again got her t&t and was running perfect until daft me turned the boost up, (boost controller was already fitted) so as im sure you can all understand im not going to rush into taking it back to any tuners yet, my plan is to find the problem, sort it then book it in for msd in blackpool, if i was closer i would have taken it there straight away, so realy hopeing someone had similar problem, lol cheers
