I went 276/317 last time i dyno'd but i dont have the scan anymore.... comp died on me
hey pro, got some q's. did you have a actual dyno tune? or did you just dyno the car. the A/F is way off seems to me. Mine is flat as can be. yours is way lean down low. you prolly could be closer to 400 rwhp with the proper tune man. Not dissin your ride. Its sick man. I love it. you got a mustang dyno around you that could tune it? they tune the car for the street not like a chassis dyno that tunes it for that particular dyno. JMO
