i got the microtuner in record time and was impressed that they snuck it through customs by not putting a way bill on it (just a plain old box) and therefore did not have to pay duty!,,,thanks guys!..so i see it can olny program one ecm at a time now i have a tde0 ecm for backup that works fine...got around 100,000 miles on it...tricked ford under warranty to put a ramaned updated version tde1 ecm in now...should i program the old ecm or the newer remaned updated ecm?..any thoughts on that?
