Going to the Dyno to get tuned tomorrow and put my BYT PCM back in. I have been running th ZZP PCM for a week and the fuel trims have been off it seems. Shot term jumps all over the place and long term fuel trims holding steady at 10.1 under all conditions. I dont know what they were before cause i didnt have the scan gauge installed. Has anyone else had this experience with ZZP PCM? Im running the stock airbox with K&N filter and mod. Im putting in the K&N when I get to the shop to get tuned.

My fuel trims are all over the place also. I'm suspecting mine are due to an Injen intake, but I don't know that for sure.
I've been on the ZZP PCM for 2 years now.
