you might want to read the stickies in the tuning section ! That jet chip you have if it came out of a 93 vehicle I doubt its programed in the correct definition and may cause your vehicle to run in lhm.

Ofcourse a custom tune is the way to go buuut.
Take out the Jet chip and install the factory 350 chip. You can bump your timing to 10* maybe more. If you know what to listen too, unhook the knock sensor.
Use 93 octane. Bump your fuel psi to 50ish.
Do all this at the track or the dyno to find the sweet spots.
There are tons of lil things you can do.
