2003 low boost
I have a 2003 6.0 with low boost at lower rpm's and at 2500 rpm it will get to 16-17 lbs. Two codes show up: P0670 & 132B. I am sure it is something I have done to cause this situation. I did an EGR delete and an oil cooler replacement. Short of a complete redo of what I have done I really do not know what to do next. I have read of a smoke test at 20 psi, i have a smoke machine for gas engines that does not get anywhere near that high of pressure. HELp with some practical ideas please.
