I have had issues with cold starts for over a year now. Smoke tested it... no vacuum leaks. got a tune still happens replaced map sensor,O2 Sensor, ECT sensor cannot figure out what is casuing this. I have a CAI and Ktuned header with catback exhaust. Is anyone able to look at logs and calibration and see an issue?

Did you let your tuner know about the issue?

Post the log and calibration file and I can take a look at it.
