The other thing you have to remeber is Dyno's from garage to garage can varie alot in there readings.

And to confirm that your reading is okay!! My Stock 21 had 46HP by the time i spent some serious cash im now looking at 58hp, the mods i have are, HRC jet Kit, Modded Box, HRC reeds, cages, stuffers, Tyga chambers n pipes and i have had the full derestriction done (wire splice) ! ! so i would say your doing fine!!!

here is a before and after shot and youll see 46hp at 10500 rpm
