I purchased their maxd-out flasher with 5 maps, up to stage 245R, for my 2015 FIST back in MARCH, but they still havent been able to deliver anything but stage 1. It seems ford did something different with the 2015, causing problems with flashing, thats why would like to hear from other maxd-out users with 2015 FIST. Pumaspeed arent really that informative, about whats going on, even though I tryed to get answers.
