Default Re: 2007 engine does not run like 2006 engine.

Def hard to overfill, not smart on their part. As for the calibrations the 07 likely(maybe not) has the latest software already. I myself have never noticed any difference in the model years. As far as i know all engines are assembled by hand(dont think a robot could do it). A slight change in exhaust routing can cause significant changes in percieved noise. We have run into many trucks that after hours of exhaust tuning with weights hung in various spots and slight mods to satisfy customers yet the next truck built the same way has no problems. Tough call and will likely end up as a nff(no fault found) but as i said at least your concerns will be on file if it turns out to be something more
