No melting, dude. The 3200 gov spring only allows your truck to make power up to 3200 rpm. So, when you're cruising down the highway and you need to pass someone, you wont have to stand on the pedal, instead your truck will accelerate with ease. Plus you will notice better throttle response just toolng around town. However, turning the full fuel screw in too far will indeed raise your egts alot, potentialy melting a piston. As long as you only turn it in a full turn or so you'll be fine. Also pay close attention while you disassemble your pump, so you get the indexing of your throttle lever correct when you put it back together. If you don't mark the position correctley and put it together in the wrong position, the motor will either not start, barely start and run like crap, or if you index too far advanced you will experience runaway, which will potentaly blow up your motor. But if you have a helper around when you finish puting the pump back together, have them start the truck while you stand ready at the turbo fresh air intake (remove the tube frome the turbo) and have a clean chunk of 2x6 to cover the turbo air intake. That will starve the motor of air and it will shut off. Basicly the throttle index has to be in the "sweet spot" to run right. Just follow the correct steps and you'll be just fine. Also, keep asking questions on here and we'll all get ya thru it.

absolutely! gotta love having choices... grinding your own stocker only goes so far... especially when you have to add a little extra metal and the welder gets away from ya; having a two piece fuel pin doesnt work well at all.
