So far, I'm not pleased with how SLOW that thing takes to download the stock tune and upload the canned one. It may be the fact these new PCMs are smart type compared to me old F150, but my SF3 I had for the truck was able to download the stock tune, make adjustments to the custom tune, and upload the tune in 5 minutes.
You can ask Nic, we sat there for about 15-20 minutes to change from stock to preloaded. IDK if this was becuase it was the first time, but I will be flashing back to stock this weekend, so I'll know if it is faster or not a second time.
Also, the touch screen is cheap crap. I can see that wearing out FAST.
Other than those things, I haven't found a problem with it so far. Haven't dug into it though.
