I doubt you will see any substantial difference on the dyno. Since the flow of air around the intercooler can't be the same as when you drive on the road and therefore not be able to cool the air for the intake as it will be on the road.

I had that experience on my 330d with bigger IC. Almost no difference on the dyno. Only 2-3Hp and 5-7Nm more. But several test with a racelogic box with accel. from aprox 50km/h to 150km/h have shown aprox 1.5 sec. improvement from OEM IC to bigger IC.
This also corresponds to my butt dyno which says that the car has more power from aprox 80km/h all the way to the top....

Btw, I have not fitted the DPF removal pipe yet. Hope to get it on in the first week of the new year.
