| about the problems with the dynapak and using these results as evidence, but I figured it was more than anyone would want to know. :) THe dynapak is only loading the car with the equivalent of about 1/4 the mass of the vehicle if it were on the road. This poses some tuning issues because the midrange response is severely impacted by how the dynapak operates. The turbos are having to play a severe game of "catchup" as the engine RPM swings too rapidly with so little load. It also directly affects how the fuel and timing maps are accessed and you can end up tuning the wrong areas of the maps if you aren't aware of how all of this plays in. Here is a dynochart from a Z with teh same turbos and very similar mods. 
DynaPak is teh suck.
