Might be better off in the 94-97 OBS
What would your power goals be and what do you use the truck for? Have to have both these answers.
For performance mods that you could still tow whatever with, get the following in order:
3 pillar gauges (EGT
, Boost, Trans Temp (if auto), Fuel Pressure (if manual))
PHP Hydra Chip
6637 intake mod or S&B intake or AFE intake
4" Diamond Eye or MBRP exhaust
upgraded valve body and maybe a torque converter (or full built trans) OR if manual, then just get a South Bend dual disc clutch
Electric Fuel sytem from Irate (not absolutely necessary)
Intercooler (not necessary unless EGTs
and/or intake temps stay high)
After that, if you want more power, you can do a bunch of research on bigger injectors, bigger turbos, fuel systems, upgraded HPOPs, camshafts, ported heads, head studs, pushrods, valve springs, IDMs, and on and on and on...
