alright guys, i got a 2006 6.0, 150,000 miles 4" lift on 35's, other than that its completely stock. i had all the studs done and all that jazz, i just recently welded up the egr ( cheap egr delete). i figured while we were doing that, lets buy a rebuild kit for the turbo , i took it one step farther and got a upgraded wicked wheel 2 for the stock turbo. i aint rough on the vehicle and not looking for a race truck but i swear i remember getting around 30 psi of boost the first 6 months i had it. no codes but egr , its basically deleted, i do not have a programmer or a tune on it yet, just looking for better fuel and maybe a little bit more umph. at this point i am confused, i cant get the boost over 22 psi, i rebuilt the turbo, upgraded the wheel, and not one bit of a difference. does the computer have a boost limiter that i need a programmer to delete? i got no leaks, it runs smooth. but with the wicked wheel 2 and the turbo rebuild, i thought i could expect a little more. any ideas
