Here lies my problem,had turbo wastegate repaired yesterday as it wasn't seating properly. Wastegate rod which goes thru the housing was removed to tack bearing sleeve from the inside as this had moved slightly,so the actuator connector on the outside has been welded back on,at(i suspect) a very slightly different angle to what it was originally. I'm guessing tis is why my boost figure has dropped slightly,this is why i figure altering the actuator rod slightly will return it to the original boost setting eventually(trial and error i know). Can't get it set anywhere"officially" before Saturday cos i'm on 12 hour days! Any advice more than welcome.
