Making the UK Fatter
Apparently HD has it's own map for running top off now. Does any one know the part no. for use with 16g and SE filter? (UK dealers not aware yet)
Thanks for reply, I have done some searching here and it would appear that althgough they state both can be used, it will cause it to run a bit leaner with the top off, so a fueling tweak would be required.Motown_VROD said:The new 28Tooth / SE Exhaust / SE Filter map is designed to run topless or with the top on. Search the part number on the HD website.
