Check Engine Light

[Galaxiedrvr]

Hey Guys,

I just installed a C&L Street kit with the 7140 preditor tuner (on my '05 mustang gt) and I am now getting a check engine light. My question is, my tuner only listed 93, 91, and 87 octane tunes, should their be a tune specifically for the C&L system? I am in Cali, and currently running the 91 octane performance tune. I believe the revision level is 36 on the preditor. Any info will be appreciated.

I will check the exact codes after work and list them.

thank,

Go to Performance tune>select C&L street kit>Install tune.

All set.

Thanks

Am I in danger of hurting the vehicle with the 91 octane performance tune? I will change the tune as soon as i get home (about 25 miles) and I will baby the car home.
