so basically leave the turbo alone ? maybe just a little more fuel ( i think to do that i need to pull the pump and have it rebuilt for more pressure ?)is it worth putting in bigger injectors and who would no what to replace them with..lol thanks guys. Any body left alive in California that can or knows how to work on these and get the combo right? ( a shop )

Ok ,well it runs fine just slow.I want to add a air-air cooler,and what else makes sense to do ?? bump up the fuel pump ? bigger injectors, BIGGER turbo ?? what turbo would work better. I read that the turbo i have only pushes around 7 psi...Any help would be great.And were to get the parts .Thanks guys..
