I am not sure what the deal is so here it is. I tuned my truck to stock and updated my livewire to the latest tune revision and firmware. I loaded my new custom tune and reprogrammed the truck. I now run hot and smokey with a max of 30psi at full lock up. Its been a while since i drove it like i stole it but i was getting 40+psi. I talked to sct and they recommended reloading the tune revision and firmware. I did that and still the same thing. I then went back to stock and took the truck to ford. They told me that i was getting 32psi stock and that is the correct boost. They said the reason for lack of power was my air filter was dirty. Indicator shows half way to red. So they said lack of maintenance and charged me a 150.00 diag fee. I cant get the factory boost gauge to even read 30psi. Any suggestions on what to do or what the problem is?
