I've seen some pretty nice torque curves, C's , Wolfmans smoother then mine in the bottom midrange area.I have also seen some A/F ratios that scared me.Why haven't I flashed ?well a friend of mine has the software and a dyno,when he's ready then we will see what can be done.My 2012 and my son's 07 have both done a lot of dyno time at another friends who is a very respected pipe builder, both bikes have custom maps and very respectable numbers.Guess I'm old school but I'll be patient and wait until I can get back to back torque curves and air fuel ratios
