You havent even maxed the pump.They can burn up an engine.
I have pretty much maxed my pump, the full power screw is my idle screw i have it up so high, my idle screw got backed off, then i forgot to tighten the nut, now its almost out, its in just the right spot so i can't get to it with a flat head. So i have to have the full power up enough that it keeps my idle just right.
The stock fuel pump can burn up an engine.

see if you can reindex the throttle lever.Move it counterclockwise one tooth on the spline,bring your idle screw back.Then turn it up some more.It wont work unless you get the idle screw back in.This sets your gov spring tension.If you dont youll have a dead spot.Is the afc maxed out?If so maybe check you egt guauge and thermocouple lead.

your not maxed out either....... the average guy can only do so mutch i had my full power screw 1/4 turn from runaway took the pump off and to a shop they turned the FP screw out back to almost stock and did internal **** i dynoed 43 hp more with the shops tune than with the FP screw alone then i got the air dog 165 because the stock LP wouldent souport it and turned the FP screw back to runaway after the air dog another 36 hp on the same dyno thats 79 Hp in pump mods but at that time i had over 12 hours in pump tuning any idiot can turn up one of these trucks but the guy that takes his time to tune and get it all right so all the mods work together with a high efficency rate gets the most bang for his buck

Don't forget about your tranny. More power is great, as long as you can get it to the pavement. Shift kit and TC would come in handy, I reckon. What about adding more air as well, since you have big injectors and a bigger turbo, maybe trick out your cold air intake. Bumping (or spacing) your timing would help too.
