Looking for some feedback as used sleds are not worth anything....Have a 2010 M8 and looking for feedback on switching the 925 over to my 16 M8000? I have new top end, gaskets etc so trying to eliminate any surprises with mapping on programmer V? The clutching is BMP and currently using 74 grams on a stage 2 speedwerx kit with v force reeds. . Ride from 2000 to 8000". I have been told that even though both HO engines are the same, will be a hassle getting the 16 to run correctly? RK TEK have been great sending me a suggested map from a boondocker BUT current experience has been last 2 trips with the 16 with speedwerx stage 2 has been off as I cannot get the correct map? So, looking for some "expert" advise on if I should switch top ends, clutching set up? stock exhaust or current speedwerx fat daddy with 2 inserts and clutch weights or do what my friends say and leave the 16 stock? I feel the RK TEK has been bullet proof but looking to just have a turn key set up. Thx for any advice or opinions.
