So American Muscle is selling the MPVI3 for the 2003 2004 Mach1 Mustang. I called the tech line at American Muscle to verify this was correct and they said the MPVI3 was released it a couple days ago for sale on their site. I bought one thinking that it was finally ready for the EEC-V but when i registered the device on HPtuner site, theres no tune file available for the 2003 mustang. I have a read only file that Tony Gonyon sent me awhile back when i was thinking about switching from the Moates Quarterhorse to HPtuners. The question is does anybody know when the tune files will available for the 99-04 mustangs? Also will i need to send this back to American Muscle and get a refund?
