HELP! P0700 U0073 after dyno?
Just had 1 7/8 Ts headers and x pipe installed
Then got it tuned with hp tuner
After had misfire in 3th cylinder, new plug fixed that
Then mustang dyno
After dyno got codes P0700 and U0073 Car wouldn’t shift out of 4th gear. Turned it off, waited a few minutes, restarted car. Shifts fix now but codes still on. Is this just bc of the dyno and back wheels going 120 mph when front wasn’t moving?
Also what do base c7’s pull stock? Figured I’d get more from headers than I did.
Thanks
