I have a Cummins ISC 350 and a Silverleaf, which shows a maximum boost pressure of about 23 psi (and always has). I just read through the thread on Charge Air Cooler for the ISL and saw references to 29-30 psi. What pressure should I expect to see for the ISC?

You are correct in that the ISC will max out at about 23 lbs of boost. The ISL is a different engine which uses a Variable Geometry Turbocharger and the boost pressure will max at about 29-30 lbs.
