So far we have 2 independent dyno runs that have produced +15hp(Fly M5) and +11hp(M5CCibro) from the deletion of the filters alone. I agree, still aesthetically pleasing to the eye, but a real performance upgrade? Questionable.
The part of the chart that I thought was most interesting was not the top-end HP/TQ, but the increase across the range...and, for the keen observer, the Akra actually took a bit of a loss in this regard. So, I say, that some of the HP gains on my car are due to "adaptation" and the filter delete
