I think my turbo is going??
When I accelerate it used to be like a rocket, now very little response. I can hear the turbo whine but not any boost in power other than that of normal acceleration. It starts and runs fine..I have noticed a slight hesitation in the 50-60 MPH area. The ECM is 1 year old. It is an 02 Dodge 3500, 258,000 miles. Any help is appreciated...Doc

hmmmmm after reading some of these posts I am thinking it might be the VP44 going south...had it replaced 125k ago....

Beg steal of borrow a mechanical fuel pressure gauge to see what is available at the VP44. These injection pumps need lots of fuel to survive. The factory lift pumps are notorious for failing, and barely provide enough fuel flow. You want less the 20 PSI at idle, but never less then 10 PSI, especially at WOT.

I had the pump placed in the fuel tank after the first one failed...Dodge reccomended that I do this...said they hardly ever fail when in the tank. Nonetheless I will take it and have the fuel pressure checked at the VP44 at idle. Should be below 20 but not near 10.....I checked the odometer for codes and there were none. Doc

so when the fuel pressure is checked..it will be around 20 from the lift pump in the tank and the same at the discharge point from the VP44? Or is there a difference in the readings? Is it approx 20 from lift pump side to discharge side of VP 44?

You need a good pusher pump, a fuel pressure gauge, and a draw straw to fix yourself up real nice... and hopefully for your sake your vp still has a few good years left in her.
