For comparison, I did some dynos back in June on a Dynapack. This included a 100% stock dyno with Procede removed:

My AFRs were leaner but you will notice that the AFRs were actually leaner stock than with the Procede. This was on 12-17 Maps so quite a bit has changed. I plan to go back for another Dyno with Rev 3, Helix IC, and Downpipes installed.
