Your injectors are good for 375ish HP with a perfect tune If they are in top shape, remember these trucks are over 20 years old now.

 

A gov. spring makes them new trucks to drive. That would be first on my list of things after gauges and stuff.

 

most deff if you just want an extra 150 or so horsepower i would do pump mods fuel pin and gov spring butt GAUGES FIRST!!!! and then a good torque converter or clutch and alot of extra air butt every one is different build you a truck you want my buddy drives a ppumped no i/c first gen he uses a hi tech turbo it spools good and he can turn 50 psi butt the truck is no where close to stock if your not wanting a 400 or 500 horsepoer truck an hx35 should be good i run one on my truck and i like it butt that is just my opinion and everyone has a different one good luck

 

once again, thanks ya'll, what i have done so far since these tips has been to install the gauges, i turned the afc screw up a few turns, i turned the factory fuel pin about 120* clockwise from stock, and tomarrow i will be turning up the full fuel screw. I also turned the star wheel 3/4 of a turn clockwise, but didnt notice much from that, from what ive read the adjusting the starwheel doesnt really change power? just makes the turbo spool faster why does turning it change how fast the turbo spools, and did i turn everything the right way?

I still have to do the kdp, but i need the truck this weekend, so that will have to wait a couple days, next week it will get done for sure :/

Ive also read that adjusting the valve lash makes a major differce? how long does it take and how hard is it to do?

Ive heard about changing the timing? how would i do that?

Thanks for all of the help you guys

Also on order next week is the "366" spring and the Denny T stage 2 fuel pin

Ive also heard that my getrag will have many problems :/ any tips on that? and how long will the stock clutch hold up with these mods?

 

there is a nifty video on youtube about the timing on first gens watch it it is easy to do you need a wood block a ratchet stop and a wrench and you are good to go
