I able to do it with the C&L CAI without running lean. Than I drove it 300 miles now it failed OX sensor not ready, evaporative system not ready and Catalytic converters not ready. I hate to take to a dealer I'm afraid they will make a major project of it. The research I did, states they should reset in 100 miles.
Has anyone encountered a similar problem or has any input what I could do next.

The thing I don't understand if the stock tune is bad shouldn't the Bama tune activate the sensors or opposite way around.
This reads better than a Steven King Novel.
Hopefully the re-flash works and THANKS for the information. I'm waiting for the snow / rain to clear up and I will schedule appointment.
