DavidYeah im thinking this also but the cat was deffinatly causing it not to boost above 6 psi with the 10 psi tune in.The rods still on the turbo and it doesnt look bent so the flap might not be covering the hole? or the actuator itself could be stuffed. ill check tomorow when I take the dump pipe off.

ENV-355 Member 8 Member For: 16y 11m 19d Posted 24/05/08 04:40 AM Author Share Posted 24/05/08 04:40 AM just to rull out a few things we swapped over the coils, wastegate actuator solanoid, boost preasure sensor with some spares we had and replaced the spark plugs. Its still slow to come on boost so its a wastegate/actuator issue for sure. just waiting for the car to cool down and we'll take the dump pipe off and see what the wastegate flap is doing.

ENV-355 Member 8 Member For: 16y 11m 19d Posted 24/05/08 08:09 AM Author Share Posted 24/05/08 08:09 AM problem found.The bush on the waste gate flap has broken and is hitting on the manifold and would let it the flap shut. Needs to be tig welded and should be all good. A blocked cat was also the problem.
