Cambelt on my cossie snapped a couple of months ago (long arse story so wont bore you with it). Bent 6 valves. Mark kindly let me do all the work myself at his new premises So lapped 6 new vales back in and put the car back together. Fired it up all is ok. Mark took it for a test run and it wouldnt boost over 2 bar. Before the cambelt snapped we saw 2.4 bar. Absolutely nothing has changed, so am confused as to why the boost would not be there. Mark had to give the acutator a good old wind to get the boost to 2.2 bar. I want my original boost figure back

Anyone had this problem before? The actuator is -34 and hasnt even covered 500 miles. Could a weak spring be casuing this, or can anyone else shed some light. I defianltely have no boost leaks, thats all been checked.

Any ideas?
