Anyone else use that Dyno recently that thinks it was reading low?

We recently dynoed a couple cars that made ~8% less HP then expected. Didn't trust the numbers as one of the engines was a fresh build that we had engine dyno data for so towed the cars over to another Dynojet on the other side of town, and they made the HP expected. Long story short, the first Dynojet had fallen out of adjustment and the brake was dragging a little bit.

If the car feels strong and all the correction factors are the same as the last Dyno, I'd try and find another Dyno. Something strange could be happening but those Buckley headers are supposed to be very good and I have first hand experience with the HRG branded stepped headers of similar concept to the Buckley's (the HRG's utilize a second step, and anti reversion chamber combine with a very trick custom collector instead of the ubiquitous Burns but the design principles are similar as would seem the results) and they have been good for 10-15whp over any other headed we have tested so your not wrong expecting more power if the engine is indeed still healthy.
