preditor u7140 updated to latest
05 ford mustang gt i filled the gas tank with 93oct took out insert and tuned it first to airiad 93oct firm shifts and right away got errors and check traction control so i retuned it to airaid 91oct and got 4 error codes anyone have same problem should i just use 93oct with insert in or do i need a custom tune

The firm shift tune disables traction control, so that is normal, but what were the other codes? Read the codes and post them up, but if you decide you want a custom tune, we can help there as well.

The codes im getting are(mass air sensor is in proper direction and used 93 oct)
P0104
P0171
P0174
P1000

Check for leaks

P1000 will reset after some driving (there is a specific set of driving instructions from Ford, but if you just do some combined city + highway it should clear itself after 50-100 miles)...the other P codes...good luck!
