Is it safe to turn the star wheel and full power screw with everything stock except for gov spring? If so how much can i go? Thanks for any info.

 

Yes! full power/ full load screw is where most of your power comes from! I turned the starwheel all the way down removed the nylon washer, rotated fuel pin to the deepest setting and screwed in the full load screw (back of pump) in like 3.5 turns on a bone stock truck and it made a world of difference!! You'll really see a big difference in top end power with the load screw turned in, in my opinion. all the other mods really seemed make around town driving more enjoyable! Hope this helps

 

be careful with the full power screw. go in 1/2 turn increments (with the truck running) and rev the engine after each increment. If the RPM's dont come back down like normal then you need to stop and turn the screw back out 1/2 turn. if you go too far the engine can rev out of control.

 

does removing the nylon washer do anything? i thought it could only go down so far?

 

where is that at the washer

 

in the afc on the fuel pin

 

yes, i thought it helped quite a bit at full throttle!! It lets the pin travel a little further then it normally does.

 

Im having a hard time turning my star wheel. the pump was just rebuilt and since then it wont turn. I tried tapping on it with a screw driver but that makes me nervous. any ideas?

 

do you have any other upgrades other than on the pump, if not that is exactly what i gave done and i might do that also. thanks

 

Um, safe on a stock truck to just start turning screws, no.

Thsi is better, need to watch for run away, other wise you will be very upset with a conecting rod hanging out your block. Take the inlet off the turbo and get a 2x6. Have a friend stand next to the pasenger side of the truck. after you turn teh full power screw 1/2 turn snap the throttle, if the RPM's hang or come down slower then usual turn it back half a turn. If the RPM's cointinue to climb after you release the throtte quickly put the 2x6 over the turbo inlet. Watch your fingers it WILL suck them and and WILL cut them off. If you hit a true run away this is the ONLY way to cut the engine off. Turning off the key will do nothing.
