Just wanted to give a quick review of the PHP FICM rollback. I went ahead and sprung for the Gryphon programmer that I can keep for a handful of reasons. I was unaware that it came in the form of an Edge Evolution type box (without the Edge label). Bonus! Now I can monitor many other parameters that I never cared to install a gauge for!
As far as the performance aspect: So far, absolutely wonderful! Couldn't be happier. Once upon a time, I had the VXCF4 strategy, and was "upgraded" to the VXCF9. I know I've gotten used to it over the last couple of years, but I don't remember my truck ever running as well as it does now. I went straight for the Hercules tune, and it is very impressive. Throttle response is right-on, the truck feels "light on its feet". There is definitely an economy improvement as well. I know the dash isn't accurate, but for my normal driving where it usually says 12.8, it now says 15.5. Money well spent as far as I'm concerned. I highly recommend this product to anyone who wants to get back what they know they lost in their 6.0 with Ford's update, plus some.
