A 2.6, tune, secret cams, header, and 2.5" catless exhaust netted me 14.4x's. So with what you have, just get a smaller pulley meth and tune. That should put you low 14's easy. Cams could put you into high 13's My GMPP kit injectors were almost maxed with the 2.6, so you'll probably want to go bigger.
Edit: I was seeing 9psi consistently.
