Had good numbers on the dyno and my A/F was in good shape. I don't have the Dyno Graph but I have the numeric print out. (Printer connected to the dyno was acting up so I have to go back to get my graph)

SAE Corrected
Max HP = 452rwhp (stock h-pipe)
Max TQ = 486

Starting at 3200rpm my A/F was 12.9 and slowly dropped into the 10s by 5000rpm. (YDH1)

We pulled some timing out(-6) and richened up the predator 1 point. I was worried about being lean but I was right where I waned to be - SAFE. Did three pulls with some different combos with the predator and I was happy with the results. My combo gave my just about 100hp gain over my stock dyno run of 357rwhp. I can't complain about that. :beer:
