hey all new hear and to diesel engines i have a 1994 chevy 6.5l turbo diesel and i pull a 6,000lb's camper . i have a question about the truck when driving a long at 1/4 throttle the truck acells pretty good but after that it dose not change it dosen't speed up any quicker or pull any better is this normal.

Possibly - a set of gages, Boost and EGT, can tell you more about what's going on.

Air filter, fuel filter, fuel quality, all play a part in reduced power where there are no DTC's to explain it.

Read thru the FAQ's, go thru the checklist as a general preventive maintenance routine.

Post your results, and welcome to the forum

he thanks getting some gauges for the weekend

Does it rev up under no load? or does it only do this under load?

ok here's what it dose when driving along an you push the throttle a 1/4 of the way down the truck picksup rpm and speed. If you go any further with the throttle it dosen't pickup any quicker it stays the same as 1/4 throttle .In any other veh i ever owned when you put it to the floor it get up and go faster then if you only put the pedal a 1/4 of the way. so basicly should this truck notice a diffrent in pickup from 1/4 throttle to full throttle

Yes.

info
