Yep I agree everything I tune I give it more line pressure makes stock tranny shift so much better, better shift quality and feel.

						mine shifts hard from 1-2 with 10psi still added in the tune. i dont even have the hd2 just the vette servo. like they said above just set the pressure back to stock. either add pressure manually (shift kit) or electronically(tune) not both imo
