So since Xtreme's dyno has been down forever I went off in search of another Factory Pro EC997 dyne that I could have my bike tuned on (found one at High Velocity in Montgomery NY). I just prefer them over Dynojets for various reasons that we don't need to rehash
Anyway, the bike has Full Yoshimura Ti R-55 system, Factory Pro v-stacks, GSXRTUNE.com unlocked ECU, K&N filter, Bazzaz ZFI-TC.
I wish I had a baseline run before I did the mods but all I have is tuned and untuned runs. So only about 2-3 HP additional a peak, but some big dips in the mid and upper-mid were fixed.
106HP on a Factory Pro is about 120HP on a Dynojet give or take since they skew the numbers.
So according to them, 106hp is a pretty healthy 600:
