Did an egr delete and dpf delete to a friends truck tuned it w\ sct from innovative ran great the first week now its only making like 30 psi of boost as opposed to 40 at first and it doesnt smoke Iike like it did at first. I know smoke isnt power but it seems like its not maintaining fuel pressure. I drove it with scan tool on it the actual fuel rail pressure follows desired the vgt looks good only code is overboost. Its only got 24k miles and the dealer just serviced it at 22k its an 08 btw. Just want to make sure im not missing anything obvious. Stock aircleaner as well.
