Mine is right at 40psi. Would the shimming the fuel regulator mod bump my fuel pressure up enough to be in the 50-70 range? I took the fuel regulator filter out and blew it out and cleaned it up and the truck is still doing about the same.

Well I guess got through taking all the fuel lines off and blowing them completly out with a air compressor, and still no change. I have already changed out the fuel pump, thinking it was it. Could it be the injectors, maybe have one not spraying right and throwing the whole thing off? If yall replaced injectors would yall go with stock replacment or perforance aftermarket ones? And how hard are they to replace, I know their under the valve covers but I didnt know well their in there?

Well if you have a new pump and clear lines the you could have a broken spring in the regulator. Did you try shimming it yet? Its very unlikely you have a bad injector. if one was dumping fuel you would have lots of white smoke too.

I havent had time lately to mess with my truck to much but Ive made some time lately and have been working on it. Got some more stuff to add to what its doing, whenever it sits for as little as a few hours and I crank it and just go, while im driving it will drop all rpm's back down to bout 600 and I can press the gas pedal all the way in and it wont do anything for a few seconds and then it will start to gain rpm's again. It does this for a few minutes till it seems like the truck "warms up". It will do it everytime unless I crank it and let it just run for about 10-15 minutes. If I have it in neutral and hold it at 2000 rpm's after about 30 seconds the truck starts to shake "feels like an old muscle car with a cam" and smoke just starts pouring out of the exhaust. Seems to me it only does it in the high rpm's ranges.
Any idea on what it might be? What would a vacuum leak do?
