"DYNO" Numbers For SOFTAILS
The operator should use the force scaling option when he prints the sheets. If the HP and TRQ line are scaled the same it gives a better representation of how the bike is performing.

Just got my bike back from the dyno. I am floored at the results. It pulls sooooo friggin hard. Also, no compression releases... just using the 574 easy start crane cams and they work like a charm.
107" cylinders
No Headwork
574 Easy Start Crane Cams (Chris "Rocket" Rivas endorsed cams)
CP Pistons (10.75:1)
Big Sucker (extended filter)
Big Shot Staggered
PC111

I have an opportunity to buy a Pro Pipe 2:1 at a VERY good price so I am thinking about jumping on it. Do you guys think going with the Pro Pipe will get rid of that dip in my torque curve above?
Also, is it necessary to get the bike retuned after putting the new pipe on or could I wait a little while to do it?

2/1 exhaust improve low end toque performace there's a good chance you will see a rise in toque at lower RPMS and just might help the dip
New tune
Took my Rocker with the Hellraiser build back to Fuelmoto for some pipe testing and found some more power. Switched from a V&H 2 into 1 Big Radius to a V&H Pro Pipe. There are only a couple options out there that fit this bike with the diameters that we needed. Got 5hp and 4tq more peak and 8tq more early in the rpm's. New numbers are 126 hp and 131 tq. To compare, my original dyno sheet is post #852.

Dyno for the new set up:
107"
574 EZ start cams
Big sucker
V&H Prop Pipe Chrome
Direct Link tuner
And here is a comparison. I had a V&H Big Shot Staggered and a PCIII. So the only thing I changed were the pipes and the tuner.

But I certainly feel the difference in the pull of the bike in the 2800-3700 range. Overall, it is smoother and the power is always there.

Bike was stock when i got it and felt like a slug, had the dealer put on the Prp Pipe intake and tune it and now i have power in every RPM range- it never has loss of power!
If i keep it around 3k range it pulls the best tho.
Next i was looking at doing some mild cams like 255s

I would love to see it retuned with the bss pipes.
