Have you checked your fuel filter? Also how are your coolant and oil levels?
Depending on how that filter comes about, I would pull my injectors just to take a look at them, if they are the original then definitely replace them, if they are all around corroded and wet tipped, then I'd also replace them , but with new injectors it's usually a good idea to replace the IP (In the middle of this myself, currently waiting on my injector pump they said 3 weeks )

Well on the drive to the mechanic and the wayback it had no power but on the hills its bad it takes all its got to get up the hill. I maxed out the fuel pump and most of my blue/white went away but have not road tested it yet. the transmission was rebuilt but the shop did not replace the pan gasket so i replaced that and the shop put a modulator valve from a c6 mustang on it. guy at a different transmission shop told me to check linkage and governor. and the truck has a turbo on it

if the engine is revving while your going up the hill .... sounds like your trans is slipping and that's the issue .. engine running fine .... in park .. does it rev right up and hold it at 2500 rpm's ... does it stumble or does it run smooth .... get back to me ... ( don't rev it up cold ... wait till warmed up ) .. get back to me .. will work this out
