At first it looked like there were huge torque increases down low, but something else is going on there. It looks like Harry at the dyno place only hit partial throttle up to about 3500-4000 rpm on runs 004 and 006. Check out the a/f ratio and see how lean it is in that area. It must be only partial throttle. Great gains up top, however. That's pretty damn good for only a rear section, not even including the mid pipe or H/X pipe. I bet the gains would be more like 18-20 hp and 30+ ftlbs torque for going from complete stillen to complete labree. Looks like Greg worked his magic again. Nice job!
