The Mustang is running again but it breaks up at 4,000 RMP's still. For some reason when I tried the different ECU it erased the tune in the DBX digital meter so that's why it would start up and then stall out again. Chris unplugged the meter and it ran and did not stall out, ran like hell but it stayed running. I put the tune back in and it ran mint up until 4,000 RPMS. Im going to try the other ECU again just to make sure nothing is damaged in my current one ( going to unplug the meter this time) and if there is no improvement then Im getting another distributor
