No tune on the truck. Without the trailer hitched, the truck 25- 27 psi. As soon as I have a heavy load the truck boost goes between 27 - 30 psi. I took off all the charge pipes, silicon hoses and check for cracks or any other signs of a leak... nothing. Put everything back on and truck still not boosting. I do not hear a exhaust leak but I am in the process of removing the turbo and i will check the up pipe for any cracks.
