HELP!!!
the ecm did need 7 updates and those were done earlier this week. no codes on the dash.

All those new parts and your still letting the soot eat the insides of that engine again just like the first time around like an acid? -- What a shame.

Either get a bypass filter on it and learn to take care of that truck yourself, or get it de-mandated asap.

Wasting all those tens of thousands of dollars at the stealerships only puts you deeper in debt. it is no way to own a truck at all, because you will never have anything to show for it.

I PM'd you my number.
