    just got back my 2007 fxst put 211 cams ported and polished heads and comp releases bored out to 103 ci the tec is already seeing numbers over the 100 mark just got to 300 miles and bring back for a final dyno tune. i see on internet other bikes with the same set up get 105 117 is this possible or is it the dyno machine it self i feel each dyno machine will produce different numbers o and the tec is a master dyno certifed just my opinion.

    Numbers on dyno sheets will always vary according to:
    1.Brand of dyno
    2.Quality of air on the day
    and a number of other influences.

    Have seen 119/119, SAE, 103", Wood 9B, Dynojet 250i, with 4 tortured years of service on the bike.
    Mid 120's on the 107" combo's, same/same.
