Mopar computer running very rich

[Toronto_ACR]

I have a 2002 ACR with the new Mopar performance computer. I notice that it runs much richer than my stock computer. I was told that it can cause blow by on the rings and wash out the cylinders. Has anyone experience any of this happening on their cars with the Mopar computer

no problems on my 2000. How do you know it's running rich?
