New to the group, just need some advice on how to re tune my car. Has a k&n Sri, 3” exhaust and 3” exhaust and has a base tune. Car is throwing a check engine light due to being lean.

Post the calibration file and a datalog. I can take a look at it. If you’re running a MAF tune you will more than likely need to adjust the MAF table due to your intake.

The car is running lean. I added fuel to all of the tables.
