With a good build on a 103, those numbers should be very attainable. That's why I questioned whether your original tune might be off a bit.

But, as Tunaman pointed out, you have to take dyno numbers with a grain of salt. My local HD dealer freely admits that their dyno reads about 10% less than the HD dealer 20 miles away.

 

If you look in the SE catalog, my build has to potential to make 98hp and 108tq with stock heads. I am at 95hp and 102tq, so the tune can't be too far off. LIke I said earlier, when I started seeing other people's numbers without headwork, my expcections started to grow a bit. But 10hp and 10tq would still be quite a nice result to my overall package. Never thought about the difference in dyno's though.
