hi,my friend has poorly cossie,it had a running problem which has got worse.it started as a misfire but now it has a misfire and theres no boost whatsoiever.all the pipes are on and tight.the boost gauge reads -10 when off the throttle and 0.2psi when nailing it.it drives like a diesel on 2 cylinders.i suspect a bent wastegate as the turbo is spinning and it has done a few good backfires.its a k plate sapphire which is quite tidy,but if he cant get it fixed hes going to break it as hes losing patience with it.i can see where hes coming from as its pissing me off and its not mine!
