boost is silly. It flat works. no need for big bumpy cams, high stall or tall gears. I dropped a full second off my et w/ 5.5 lbs of boost on a mild 440. And I didn't tune it much. Probably left some on the table and would have run better w/ 3.73's over the .91's I had. My next build will be boosted. You can have you cake and eat it.
