You're wasting your breath arguing with Mr. Shiftright; he never EVER admits that the is wrong. When I installed my Mazdaspeed intake I timed in-gear acceleration before and after the install. I used the same technique Grassroots Motorsport used when they tested their 2007 MS3 with the same intake- and I obtained almost identical results. Shifty insisted the test was flawed, claiming that there was no way an intake would make that much difference(Mazdaspeed claimed it added 25 hp). Care to guess what he said would convince him?
