Wow that's crazy! I know that the ecm that is on this engine is the original ecm that was on the motor that threw a rod. you might be surprised like i was, the head bolts weren't tightened down properly ' i took mine of with a simple ratcheted n socket. cesarluiscr Location Offline Junior Member Reputation: 1,359. id take my time on checking everything out. For INSITE 7.6.0 to 7.6.2 SP5, your INSITE has expired, fix your problem with this. Since the history of the motor is really really weird lol. like rawze stresses the importance of good tunning. It could be a difference between blowing the head or going trough several turbos + w.e else the shop or you want to fix thinking you are fixing the underlying issue. He told mine was very weird but it wasnt bad, told me a couple of things that i shouldnt use whats so ever and other things to keep a eye out for it till i can pay him to fix the programming. What i would do now different, is take it to a shop to pull the programming, when Uni looked at mine.

i didnt know jack sh%t about cummins or the truck!. also i didnt know if the truck got a delete kit on it.
