The stock file is very important "if" you ever need to visit the dealer. They plug in their diagnostic stuff, find the file you have foes not match what Ford has on file for a stock code. Their computer goes into full on lock out/ down mode. And if the tech is not paying to close attention it will send the info strait to Ford. Then all bets are off. Even if you went in for a simple oil change and happen to plug in.....
Stock file is real important
It's not that big of a deal, just mainly an inconvenience, but my pickup has a rebuilt title, so I could care less of what the dealer thinks. Also, my local dealer is very small, 50 miles from anywhere, in a town of less than 2000 people and only has one full time ford certified mechanic lol he knows these pickups very well as their primary customers are farmers and ranchers and diesel pickups are their only real inventory most of the time.
Benefits of living in rural America...
That being said the wAy I take it is the the way the Spartan writes the tune into the pcm it has to have a factory tune to work properly?
Was really just hoping that it would save the HS file as stock if I ever sold the pickup and wanted to keep the Spartan I could just set it back to that, but hey you can't have it all lol
