TMAX speedo calibration problem

[itsafatboy]

So i have a 01 softail with the tmax , whats on bike

116" (open belt drive)
engine pulley = 45
clutch pulley = 71
trans sprocket = 32
rear wheel pulley = 70
baker direct drive 5 speed with close ratio 1st
wheels are 17" (07 fatboy wheels) tires are low profile metzler

so the stock setting is 04352

when i ride took a GPS because it seemed that the speedo was slow and it is about 5mph slow
so i changed using the xls sheet and it made not change ,

then i took 65 / 70 = .9286
then .9286 * 04352 = 4041 so i plugged this in still no change the bike is still off 5 to 6 mph

and yes i wrote the basic setting to map and even reread the module map and settings from bike after to make sure it was the correct setting .

so then i set it at 04663 took it the other way no diff. still off 5mph slow.

So is the 01 a different animal because of the non databus stuff or am i missing something.
