I haven't been thru this whole thread to see how many SAE or STD dyno sheets there are. The correction factor used is up to the tuner. There's no hard fast rule for either as far as I can see.
The dyno is for tuning and comparing parts. The only valid way to actually compare one bike to another is to have the dyno done in the same shop on the same day by the same operator.
If the only concern is "bench racing" then I guess you could insist on one correction factor or another along with only allowing numbers in a given gear. But you still have the possibility of an unscrupulous operator fudging numbers.
Some of the top Harley performance sites list dyno sheets with both SAE and STD correction (Woods Cams, Horsepower Inc., Headquarters, Hemi Performance Engineering, Revolution Perf.,)
The reality is that the % gains thru modification and tuning is virtually identical regardless of the correction factor used.

New Performance Build
Finally after months of research, I did a "few" improvements.
S & S CNC Ported Performance Heads
S & S 106 Big Bore Kit ( Flat Top Pistons )
S & S 585 Easy Start Cams
Fueling HP+ Hydraulic Lifters
Andrews Adjustable Push Rods
Timken Bearings, new cam chain tensioners, all paired up with my current performance upgrades: Screamin' Eagle Heavy Breather, Vance & Hines True Dual Head Pipes, Screamin' Eagle Performance slip on Mufflers (gutted with Big City Thunder Baffles installed.) Fuel management by Power Commander, Dyno-Jet PCIII USB. Loaded a canned map (temporary). Will have it dyno'd after break-in miles, but according to S & S specs it should come in at around 115 hp & 112 ft. lbs. torque. Now if I could magically make the snow disappear, I could cure the severe "PMS" and start saving for ????????

Stage 1 & Dyno
Had Stage one done yesterday, and here are the results. Not sure if these are good or not. Definitely feel a different, especially at lower RPMs. Config is SE Kit, PCV, Rush 1.75 slipons, and dyno tuned.

Nice before and after...
Was it all stock for the before run? What I mean is did you make all the changes at (Pipes, SE Intake, PCV, Stage-1 Download) once?

'07 Heritage Big Bore upgrade Dyno numbers
So I just paid for the winter upgrades on my 07 Heritage. I went from a 96 to a 103 and SE255 cams (using the S/E stage 2 pro race big bore kit) and Bassani Road Rage B1 exhaust. The Heritage already had a stage 1 done so it was breathing freer along with Power Commander fuel management. I haven't had to chat with the Dyno tech or a chance to drive to the dealer where the work was done. I paid over the phone and received the receipts and attached dyno sheets in the mail.
The numbers look good but then again this is my first go round at this...what say you?
