Congrats on the nice numbers. But running the stock cat with an FI set up is asking for trouble. It will eventually (sooner then later) melt down due to the added heat, and when that happens it will create an obstruction in your exhaust system, when that happens your motor cant expel the gasses and your EGT will go through the roof risking motor melt down. If you ever notice the car feeling really sluggish all sudden stop driving it and check the cat before you start scratching your head too long.

Heat and pressure work to degrade your catalytic converter. You can move it further from the header (and thus heat/pressure) to extend its longevity. This would require some custom exhaust work and it's not necessarily a permanent fix.

Yes, I'm curious. Dyno numbers can vary by as much as 30%, from one dyno to another on different days. So, the actual numbers don't have a lot of meaning unless you know the model of dyno and the correction factor applied. (Unless of course all you are after is knowing how much hp change there is with a single part change and you do it back to back).
