One of their regrinds I think gained 10-20 hp on a stock engine at 12lbs. The other which was using their tri flow design they didn't have any dyno proof but said its better. Idk I got the one with the proven gains.
I offer to pay give anyone $50 who can proved that those cams regrind makes a different in HP on f2/f2T 3-4 years ago. nobody bite, no single dyno #, no prove whatsoever, yet they post pic .
I do agreed with Darkmx6, it doesnt make any sense, you have to add metal to gain more lift, grounding something down changes the profile. but hey , what do i know, since i never use anything than stock cam, and will stay that way. and still makes power.
use that money you going to spend on that regrind on a more sensible mods.
