so 510cc injectors are good for 510hp on std pressure.

If you turn up the fuel pressure, it gives you more fuel at the top end.
It also gives you too much fuel at the bottom end and the ECU can't compensate properly..

Haha righto. Partly agree though that you may see differences in tune (ram air effects etc) which is why we will go out and check at the track if required. However there is absolutely no substitute for the flexibility or repeatability of a top dyno with excellent datalogging equipment.The best dyno tune is never the best track tune
