finally got my car back last night after waiting for 6mths to have the engine rebuilt.

now got a turbo problem used to hold fine at approz 14-16 psi through the gears but now it shooting way above 20 +

it got a manual adj boost, but this is turned to the lowest setting.

the bloke who done the engine work also changed the ecu to one with a collins chip

turbo also seems to kick in at a lot lower revs any one got any ideas ?
