I'm not an expert by any means, but I think it has a lot to with the position of the wastegate pipe in relation to where the rear housing starts to split in to the turbine wheel. If you notice the one I posted is right down near the flange where as the ones on the falcon housing is a lot further up so the turbulence created will slow down the turbine wheel.

senna_T Forged Member Lifetime Members 15,818 Member For: 18y 2m 24d Gender: Male Location: SW Sydney Posted 23/01/14 09:42 AM Share Posted 23/01/14 09:42 AM I think checking the timing is probably the biggest clue there toad. If the turbine is being slowed then the motor can't pump the gases as efficiently and as a result timing would be retarded and I'm guessing the boost would come on more slowly too. I've never done any tuning, but could open vs. Closed loop tuning allow the timing to advance and retard like a factory tune? Or am I way off here?
