> edit: I’m going to try to pass my KA-t legally this weekend. need a new O2 sensor and a cat first. If that doesn’t work, I’ll try it as a hotrod as my EGR is not hooked up. Will that make that much of a difference?

Thats my issue with KA-T’s you don’t get hotrod by law, so if they do hotrod for you it’s actually illegal. You need a different displacement block for hotrod. Some places don’t care though. Cars without egr NOx is controlled by the cam durations/overlap and timing. I never actually play with a KA-T on the dyno. If you going to try it, run the stock cat, aftermarket cool down way to quickly. By the time the dyno is ready the cat cools off even with the car idling and then the heat up while doing the test and by that time it fails.
