Need help...new 85mm maf and 98mm lid please help if you can. I'm getting p0131, p0171, and p0174 codes after running my car at the track today with my new set up....which includes an 85mm maf and 98mm lid. Codes mention too much oxygen getting to exhaust. Also, I ran my car at the track without air cleaner. Am I getting too much air and not enough fuel (stock fuel pump)???? Any help is appreciated

You can't just throw an 85mm MAF and different airlid on there, it needs to be tuned for it properly and that doesn't involve copying the 85mm MAF table from another vehicle and just slapping it in the tune. Also removing the air cleaner can change how air flows through the MAF as well albeit slight but it needs to be tuned for how you are running it. It's going to need street driveability adjustments and dyno time to be accurate.
