Runs on offroad diesel. Has absoluetly no power under 2000 rpms. Just a total dog. Boost doesn't seem to come in til 2100 or so rpms. 6 speed and I keep abusing the clutch to keep me from getting ran over. just hit 104,000 miles on the ticker

 

mines auto but when my map sensor (just ontop of blower motor housing line running too xpipe) is plugged in its a total dog till bout ooooo 1800 1900 rpm then starts too boost disconnect that sensor and itll pick up better but thro ses light if you can live with it

 

I wanna fix it!

 

ever look at the fuel filter? check engine light? air filter? smoke? mods? need a little more background on the truck

 

Fuel filter just changed 500 miles ago. No cel. No smoke. Air filter is stock. everything is stock

 

red diesel is non ULSD so it doesn't burn as clean. you might have carbon built up on the injector tips.

 

Try unplugging the map sensor and see if that helps any. If it still runs the same and throws a SES light then you know it’s not the map sensor. Then i would run some injector cleaner with the next tank of gas. Some guys are against the injector cleaner and they say it’s worthless but i like thinking it works. Try those two things; they might help in finding the problem.

 

the red stuff is the same as the green stuff nowadays. granted the green stuff has some "emissions" geared additives. still a possibility though!

i got a question, is there a wooshing noise coming from the exhaust?

and if you can get a scanner on it, sometimes these trucks dont like to throw a check engine light even though there is a problem

 

It’s your EBPV. Its normal and it should only do it when the ambient temp is below 32 degrees. It’s to help the engine warm up in cold weather.

You might already know that. Not sure if you were being sarcastic

 

thats what im thinking ^

try unplugging the 2 wire plug that goes in to the right (if your looking at it from the front) of your turbo pedistal. see what that does for ya
