Just got my 6-pos Phoenix and have been running for a week. I think my PCM has been flashed with something other than Ford stock. I've had the truck for a month (bought from a dealer; no info from owner). Stock setting on Phoenix totally different than before w/o chip. W/O Phoenix had good perf and 19mpg, trans would shift to O/D at 40mpg with light throttle, in Park would go to high idle (1100) after 2 min. There are other that make me suspicious that this not a stock setup looking back at it.
Anyway, my question is: How will having a PCM flashed NOT stock affect my Phoenix chip performance? Is this going to be a problem? Or does the Phoenix totally take over with no changes?
Thanks! Great forum! Great service from PHP!
