Hello, New to forum have 2015 FLSTF I bought used and was told it has stage 1. Has Hi flow air and Python staggered duals. Road home decel pop like anyone's business. Bought VH3 to load map to address decel which is now gone but bike seemed sluggish. fp3 backs up the map. The map installed was 34271-12A when I look up the part number is is listed as ND-103/1690 STAGE 1,BIG B. Can anyone confirm if this is a standard stage 1 flash or is this a big bore flash and the new to me bike had a big bore kit installed? In which fp3 will do little good other than flashing back original map with decel item enabled. Thanks!
