I received my PCM back that I shipped down. Other than it being packaged differently, I cannot tell if any service was performed. No note, no feedback nothing other than the paperwork I shipped out. Odd and non communicative. Disappointed. I had higher expectations after using FRP for tuning my other truck. Of course I dealt directly with Ryan, so maybe that's the difference. I'm certain it's probably good but would have thought something would be included? Saying service performed or unit service completed.
