Installed a Steeda COI system into my brand new '09 GT500 Shelby Mustang. Cannot get engine light to turn off. Tried to mod tune for MAF; went to 5% first and then 8% - no luck. Light turned off for a short while, but now back on. Help. Thanks.

What tune is installed?

Are you running the Steeda CAI tune??

What code is it throwing?

What revision is on your Predator?
