I just found out from my local dealer yesterday that they will remap my stock computer to accomodate slipons and a K&N filter, with the snorkels removed from my airbox, for about $35!!! They said it would only take about 1/2 an hour and all I pay is labor. SWEET!! All this time I thought I was fooked because no ecu's were available for the M620's, and the one that I found out is available is like $700, not for me thanks. So anyone who just needs a little computer tune up, ask your dealer. I think it's a great deal since I won't be modifing my bike beyond the pipes and air filter.
