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.

The pusher pump may have hurt. Do you have a rail pressure gauge?
Nope, workin' on it, been leaning towards the Quadizilla FP/RP digital gauge but I read some people were having problems with them, I know the Predator does run the rail pressure up there...if its ok I'd like to post the dyno graph for some kind of analysis's..

The red line is the Predator "Extreme", the blue line is the "Tow Tune".

Am I reading that right, the difference between the 2 runs was Tow setting on one and Extreme on the other, all other settings were the same?

Thats correct, the only other thing as I mentioned before, is I have now added the FASS, the dyno run was with the Carter.....thanks

I surprised to see them so close. The Fass should help you out, also a RP gauge.
yeah me to, thats why I was looking for some educated guesses here, thanks, I'll be back at the dyno later in June, we'll see what the FASS does for me...
