SWIA
I have an 2005 peterbilt with a C15. I let it warm up for about 15 min before I take off, but it will only boost to about 25-30 PSI for about the first ten miles and after that it runs like normal with about 45-50 PSI. of boost pressure. The EGT's do not heat up at all under the low boost and no smoke. Any help would be appreciated. Thanks
