turn up the pump :} i have a 90 Non IC and i have not dyoned but i would bet that by cranking the pump a lil, putting holes in my intake and doing a exhaust i gained maybe 60 hp, in the next week were putting in a set of POD(injectors) maxing my pump and advancing the timing, and doing a 4200rpm GSK(govener spring kit) after that i want to beaf up the tranny, do a set of valve springs and a hx35/40 hybred turbo, do these to your truck(well do a clutch instead of a beafed up tranny lol) and your truck will fly

Pump mods and puting on a better intake will make the truck run a lot better and lay some smoke too. Injectors would be the next step from that. Make sure to put in some guages (EGT, Boost) to keep things from going BOOM. Other than that maybe a 4k gsk and valve springs ect. There are a ton of stuff to do so Have fun and get started.

Yup I've gotta second what BossHawg said. GAUGES GAUGES GAUGES at least a Pyro and Boost. I haven't owned one of these trucks, but I've heard with the bigger exhaust housing on the turbo, that even just turning up the pump can make them get really hot really quick. So I would get gauges before playing with stuff. But thats just me.
