Thats going to be a fun one.. I had to go search and see if anybody still made programmers/Chips for them.

Looks like Jet Programmer will work but dont expect a huge gain for the amount of money spent.

You could run 93 octane and put a 75 shot on it.
Ive only messed with a 4.3 in a 2001 S10 and we ended up putting a 125 shot on it after tuning it.

Weight reduction, 4.56 gears and a tune. It should move pretty good for a 4.3.
