HELP 01 Dodge surgeing

[sledshaker]

I have a 01 Dodge with a powerpuck, 155 injectors, bluechip and stock VP. The bluechip stays off unless sled pulling. Lately the truck wants to surge, when its not pulling a load, under moderate to heavy throttle. When I am pulling a load, it wants to surge under light acceleration, but when you roll into it, it goes away. Any thoughts?? TPS, pump, map sensor?? Thanks

Could it be too much fuel, and not enough air to the turbo? Are you running stock turbo, or aftermarket?

Running a 62 charger with a big air filter on it.

what is your fuel pressure while this is happening

It's your Turbo no boost at light throttle the map sensor doesn't see boost so its Confused.

Not sure on fuel pressure, running a air dog unit. The turbo has been on there for 3 or 4 years, why would it just now start doing this? Thanks for all the inputs.
