Default dyno problems

So I was at the charity dyno event yesterday in Spokane, Wa (it was the first one I've been to, and a lot of fun). I did however run into some problems when I got my truck on the dyno. I have an '01 Dodge 2500, auto, with intake exhaust and juice w/attitude tuner. The truck chugs out black when on setting number 5 normally but when I got strapped onto the dyno it threw up 272 hp and just over 600 lb feet of torque with no smoke at all. I got of the dyno and took it on a side street, punched it and rolled some coal. They let me go back on after everyone was done and I ran into the same problem. I'm gonna get a hold of edge tomorrow and pick their brains but if someone has any ideas I'd appreciate any help!

how much fuel was in your tank? was it a mobile dyno? if your tank was low you could of not been getting enough fuel if it was facing down pretty good

Three quarters of a tank and the dyno was fixed, in ground at the college. Perfectly level and I forgot to mention that I have an airdog 100 gph lift pump.

was it a resistance dyno? if not you wont get as much smoke, because theres no load on the motor.

I believe it was a resistance dyno. Every other truck up there was rollin coal and mine didn't let out as much as a puff. My boost was up around 30 psi, everything seemed to be running fine.

Almost sounds like the wire wasn't tapped as those are around the regular EZ numbers

The wire that taps into the vp from the juice, without it you get 65hp max as its only running timing

It was a loaded dyno but some times it seemed like the dyno didnt load. Like last year that same dyno loaded hard enough it almost killed my damn truck. This year it didnt do a damn thing on mine. And i only got about 25 lbs of boost outta my 64
