Turbo Problems
I have a 2003 f250 diesel. I recently finished taking out the cat and the muffler and replaced it for two four inch pieces of pipe. It made the truck a good bit louder but i have noticed a problem with the turbo. It is almost like it is loosing pressure and once i get up to the speed i want it stops until i increase my speed or climb a hill. This awesome happens when it is sitting in the driveway idling. Any help would be great because Im new to the diesel world and I dont know much about them

That's what a turbo does, really. The more load put on the motor, the higher your boost will be (within limits, of course). When you get up to cruising speed, the turbo won't be working as hard. Can you describe what it's doing while idling that makes you think something is wrong? Does the exhaust note change? Not sure you've got a problem here...

take it to an auto parts store and have them scan it for codes
the thing is the turbo uses the exhaust gas to spin the turbine so everything B4 it must be working correctly for proper turbo operation injectors, fuel system, air intake and so on......
To me its hard to point the problem being turbo relaited without a code or some gauges to see how much Boost it is or is not making
Do you still have an egr valve have you tried to clean it if so if its stuck open it could cause a power loss

I cleaned the egr valve. And the turbo was taken apart and cleaned about a month ago. Could there be an issue with back pressure build up since i have take the cat and the muffler out of the exhaust

could be a MAP,EBP sensor issue
they need to be compared at KOEO no more than .5psi apart
There shouldnt be any build up of backpressure with the cat and muffler gone
