Wasn't sure what to make of the results, running the Diablo Predator on the non-stacked tow tune (Lowest tune) the Puc on 90hp setting, TST on 5/3 I hit 454hp/912ft.lbs. So then I thought I would run the Extreme (Highest tune) non-stacked setting, I hit 456hp/900ft.lbs, not much better (Only 2hp difference). According to the chart it looks like Extreme setting just dropped off. I was running the Carter Pump pusher (not the FASS 150 in my signature at the time) so I'm hoping this was my problem. Any ideas on this, I can post the dyno run if its allowed for review.
