Hey everyone Im new here so give me a break if I couldnt find something, I have tried the search button but cant find much about what I am looking for so maybe someone can help me. I have an 03 F-250 with the 6.0. My motor locked up a year ago and a shop just finished installing another motor but its out of a van. I just got my truck back 2 days ago and it feels really sluggish like something is holding it back and has no power.

I have went through a few engines my first engine was all stock then I put an sct programmer in it. It cracked a piston due to a bad injector I was told. Second engine had ARP Headstuds, powermax turbo, MPD 190/100 Injectors, Airdog2 fuel/water seperator, Regulated return, egr delete, and the basic intake, exhaust, programmer. This one hydrolocked because the injector tip broke and bent 2 rods I was also told. Both the previous engines were out of an f-series pickup.

Currently the only upgrades I have are Intake, Exhaust, Powermax Turbo upgrade, Coolant filter kit, Egr Delete, Airdog2, and Regulated Return on the Stock tune. I have tried using the sct programmer to see how different it would act and I still feel the hesitation. With this same programmer and the original motor the power was crazy and dumped some black smoke, now with the same programmer and tune it has less power and barely any smoke. I also use this truck to pull a trailer a couple times a year with the stock tune in it.

So I was wondering is there any differences between the f-series pickup motors and the e-series van motors?

What can I do to increase power?

And is black smoke with a programmer bad for the engine?

I am located in Northern NJ if anyone knows a good shop that I could bring it to and have overlooked.

Thanks, any advice/info would really help.

The engine itself is identical between a pickup and a van. Some of the things that bolt to the engine, like coolers, brackets, etc, are different. Nothing that will affect power output.

The vans do have less power than the pickups, but that is due to programming in the PCM.

And black smoke is usually unburnt fuel.
