It was the PCM. Now I'm having the problem with the truck not boosting at all. Like normal driving with tunes I use to run about 7-8 pounds cruising, now I'm only running like 2-3 while slightly accelerating.

I'm not sure if the turbo had to go through a relearning process with the new PCM but it seems to be gradually getting better. The turbo whistle gets louder and louder every few times I drive it. And the boost and power seems to be picking up a little. But I'm really not sure what the deal is. No codes yet though.

I think I figured out my problem. He just said that it probably wouldn't relearn with no EGR valve, but I actually do have an EGR valve and I just plugged it back in today to get rid of the EGR codes it was giving and that was the start of when I started noticing it driving better.

Yeah the guy at my shop told me I could unplug it with the delete but the guy that wrote my tunes told me not to because then my cooling fan wouldn't work. So that's why I plugged it up this morning. I didn't know it had anything to do with the turbo.

Yeah I've noticed that. It makes diagnosing problems so freakin annoying. A blown out brake light probably causes injector problems...who knows haha.

I am having his same issue on my 04 F350. I tried the pin test and got 12.7 on pins.2&3 but I didn't get anything on pins 3&4. New here but spend a lot of time over at powerstroke.org. Thank for the help.

Souinds like you have the early MAF sensor that also has IAT sensor within it
so not all the wire are for MAF
1 wire should be V-Ref 5volt for the IAT sensor
MAF should have a 12 volt power and Ground with signal circuit
What is the Exact code you pull????????

heres the operating value per Ford
MAF 0 1.44 2.65 0.5 - 4.75 VOLT Mass Air Flow
so that goes like this
KOEO=0
Low Idel=1.44volt
High Idel=2.65volt
operating Range=0.5-4.75volt
Do you have a ScanGaugeII????????????
