"Rev. B" 18-033-07 done today

[CUMMINZ]

Had my overhead replaced today because the service engine time to change oil message came on about 1k ago. Also asked DC dealer to do "B" revision. They did that. Immediately my overhead is more responsive and am showing 17+ going down interstate and changes to 10-11 in town rather quickly. :-laf

Rev. "B" 18-033-07 Done

Just had mine done today (8/29/07) at 6593 miles. Did not have any major issues up until a couple of days ago. My "check engine light" (MIL) has been flashing for quite a while but went off when started. Two days ago, it began staying on constantly while driving. The manual says to take it to the dealer if the MIL stays on. So I did. After getting my truck home, I looked for the Rev. "B" modification label that is required by federal law, but could not find one. So I'm back to the dealer tomorrow to have one affixed showing the Rev. "B" flash has been done. I'll check mileage and overhead readings while on a trip this Labor Day weekend and see what effect the flash has on performance. The dealer service report stated I had "excessive soot accumulation" in the exhaust.
