Evenin all :)
My stock twins have always performed perfectly, but now in 1st gear the secondry turbo doesn\'t join in until 6000 rpm (still normal at 4500 in all other gears).
Any opinions appreciated, thanks.
itll jsut be a slow solenoid mate. Might be sticking - or a tired check valve. Overhaul your vac system, new lines and check valves. If you still get it you know its the solenoids.
