At the risk of sounding uninformed, can someone help explain what I'm looking at with the dyno sheets? I know it is showing torque and HP but am not sure how to read the graph. Thanks :-/

Great article in July American Iron magazine on Dyno tuning and how the numbers can be manipulated by crooked tuners

Super Trapp 2:1, SE Air & SERT. Can't post the scan (too big?) so you will need to open the Word Doc attached with scan inserted.
[highlight]97 HP and 99.5 TQ.[/highlight]

My original baseline (performed by dealer) before the Pipes and Air Cleaner were added was 87.2 Max HP and 90.4 Max TQ.
Max TQ range is now starting a little lower around 3300+ RPM vs 4200+ before the mods.

H-D
Running into some major problem getting my 06 SCUC dialed in with my new Freedom pipes, Power Commander and Air Filter Kit.
My dealer has installed everything and followed all the instructions, on the dyno the bike is only pulling 1 to 2 hp & tq over stock.
Called Freedom discussed events with Brad.
A second Power Commander was over nighted and still the same numbers.
Once again discussed all the installation with Brad at Freedom and everything is installed and dialed to Freedoms specs.
Bike pulls hard in 1st, 2nd & 3rd gear, then falls on its nose when the 4th gear pull is attempted.
Any ideas ?
This is driving me crazy
Thanks

The first thing that comes to mind is the engine may be wet sumped. If the oil pump is going south or there is a tear in the pump o-ring it can cause the pump not to pull the excess oil from the case. This would create a low power situation.

Here are my dyno results with D and D Fatcats with Ghost Pipe, SERT, and K & N high flow filter. I'm pleased with the results considering that I've had no engine work (cams, heads, etc.).

As you should be those are nice numbers and should feel really nice when you twist the throttle.

I'm not sure why, but I didn'n know if I'd break into triple digits. I was sort of hoping for high 90's.

Not to be negative here, just a comment. After reading the article in AIM about all the dyno do's and dont's, on Mikes bike, they used the first run for the baseline. The article warns that a lot of dyno operators use that first run to make thier improvements look better as a warmed up bike would produce a better base line after 4 or 5 runs. As much as 4 to 6 hp. Still good final numbers though.

You are correct however, that was only the first "recorded" run. The dyno operator (Bob)does 3-4 "pulls" on the dyno to get the bike up to temp. If he had recorded each pull the "baseline" run number would be a higher number. You can't just go by the run number.
