The tune I am currently running is attached below. when I pull my boat or just driving down the road I blow to much smoke in 5th or 6th. My 6th gear rpm range cruising down the road is 1500-1600, so if you roll into the pedal she starts puking a cloud of black smoke. If I don't down shift to bring the Rpms up I will cover traffic with Coal smoke. What do I need to tweak to lean this out?
