In my 2006 powerstroke and when i punch it it feels like i have no boost in my turbo but my gage says im getting plenty

could be alot of things. sucking air some where in fuel system. leaks in the pressure side of turbo, stuck wastegate on turbo.

Have you checked all the tubing cuplings? When mine was doing that i had a cupling that would keep sliding off just enuff that it was letting out air and loosing me boost.

there is no wastegate on a 6.0l turbo. its a variable geometry turbocharger and doesn't need it. i have never seen a turbocharger cause a misfire, the turbocharger is most likely not your problem. if you didn't clean the intake out when replacing the egr valve there is a really good chance that the egr is bad again. also, a bad egr cooler can cause repeat egr failure. also, fuel injector control module is a common cause for misfire

Sound like this has a turbo?? And this is the culpert!

Does it have a turbo? Sounds like it does. Might need replacing.

usually 1 of 2 things-lack of lubrication or a foreign object in the intake.at turbo speeds,the smallest object will wreak havoc.

P1247 means the Turbo Boost Pressure Low, this may be a turbo issue or a defective waste gate.

replace your oil pressure sensor and have a mechanic do a oil pressure test.

check the piping from the compressor outlet to the throttlebody for boost leaks. also check to make sure that the wastegate actuator is functioning properly. it may be stuck open. the other thing to check for would be an exhaust leak either between the head and the exhaust manifold or the exhaust manifold and the turbo.
if its none of those things, check the blades on the turbo (compessor and turbine sides) for damage and make sure that it turns freely

replace the wastegate vacum lines or wastegate acuator. if they leak it raises the boost. Let me know if its not that.
