Okay, so been running on the flash unit for a couple days, seems to have the cut-off problem like the TIII units do. EGR maintenance reminder maybe, like the TIII's? I didn't see anything like that in MP-Tune on the 465 cal, but I'm guessing it's not fully disassembled yet and so wouldn't show up in Mp Tune? If you turn the key off for 20 secs or so, it starts right back up.
