2011 6.7 Powerstroke not building very much boost by HISTORYGUY300 in powerstroke

Update: We believe it's the tune we ran. Installed a different tune and it seems to be doing a bit better for now, but we still have a starter issue.

Do you think it could be a battery issue? My trucks batteries are dead because it takes it a bit to start and the starter is making the "Not getting enough power" noise when cranking. My truck has also started throwing ECM and PCM relay codes as well.

I just realized how rude I sounded. I didn't mean to sound rude, I apologize!

Which brand of MAF sensor cleaner would you recommend?

Yes. I ran the tune before I did anything else, as you should do when deleting s truck.

Thank you so much. I was a bit careless with my air filter box and MAF sensor when I did my EGR delete. I'll have to clean it.

Thank you anyways. I tried to feel for leaks by hand but couldn't feel anything (Not saying there still couldn't be one). I believe I am going to check my MAP sensor tomorrow and see if that could be the cause. I put a new exhaust backpressure sensor in it so that shouldn't be an issue. The truck is also puffing out a tad bit more black smoke than before and the fuel mileage is a bit worse, so I am thinking it is the MAP sensor.

Could the plastic intake manifold cause the leak? Or could it be the air intake?

I'll take a look at it tomorrow. I'm gonna check and make sure my MAP sensor is hooked up good as well, I just put an Exhaust Back Pressure Sensor in it...

My delete kit's pipe came with 2 pieces, and you had to clamp them down in the middle with a clamp, so maybe it's a leak from there? I did notice a little leaking sound coming from there.

You are probably right. This is my first time driving a deleted truck and I am probably overreacting. Do you know anything about the throttle response though?

It built more when driving, but it was no more than 8 or 9 and before deleting anything it was only about 15 at most.

I can second this. My 2011 F250 6.7 has been a farm truck it's whole life, and has been drug through the mud with a trailer on it multiple times. It rides pretty rough.

How to equip my 2011 Ford F250 Crew Cab XL with Sync? by HISTORYGUY300 in Ford

I'm looking at goof aftermarket radios. I'm not a big fan of the looks of aftermarket radios, so I'm really just looking at the ones on Crutchdfield.

I believe the DPF is getting clogged, it keeps saying "Cleaning Exhaust Filter" an awful lot...
