I have the Pro-flow cats with my DynaTech LT's. No issues. This is running the STS kit and a rich tune. Part throttle is about 14.5-14.9 to 1. WOT is about 10.6-11.3 to 1. I drove the car for a few days before dialing in the tune and it was running a stinking pig rich 8.7 to 1 !! Cats survived with no problems.

My part throttles are Stoich.
You are running a little lean to go up to 12 or 13 PSI ... a bit agressive. I take mine down to 11.4:1. I used to do 11.7:1 at lowest AFR, but too many people were saying it wasn't enough for in excess of 10 PSI boost.
