It's not misleading at all, if you look at ANY result on the ALLSTAR dyno they are always down on midrange compared to most other dynos...
For instance my car only makes 127rwkw at 4000rpm on the Allstar dyno but 196rwkw at the same rpm on a Dyno Dynamics dyno. That was on the same tank of fuel with about 50km driving between the 2 dynos!
Another RB25 neo makes 135rwkw at 4000rpm on the Allstar dyno but 220rwkw at the same rpm on a Dyno Dynamics dyno...
Then we could compare my set up to batterys, both same motor, same fuel, same turbo, same manifold, same gate... Same top end power on the same boost on the same type on dyno. Plus same boost response and build up on the road. His makes 200rwkw at 4000rpm (funnily enough almost exactly the same as mine on a dyno dynamics) and mine makes 127rwkw...
Take from it what you will, I have no idea why it is like that but every single result I see off the Allstar dyno appears to have shit mid range compared with other dynos which explains most of the "100rwkw down @ 4500rpm"
