no, i didnt red light it. i really dont know how to figure that out. a bunch of my runs that day had a r/t of .022-.025 and my buddies said it was pretty good. but, yeah.. i really just have and intake and exhaust and nothin else. i dont think taking my back seat out shaved any time at all. but, i did(for the first time) use the 93 octane gas and the octane booster. that might have helped???
