Turning a stock pin is not much difference. All 3 of the ones I have turned were almost set to the deepest anyway from day 1. Don't just turn it without looking where it is. My 92 was about 10 degrees from deepest. An aftermarket M+H pin gave me 5 or 6 psi more boost. The only drawback on a deep pin is the chance of it making the pump leak fuel.
