Redline made more power, but I think it is because I got more boost built on that run. The settings are all listed below the graph.

Were all runs made with the Smarty stack?..... and 5thg gear?
Did smoke clear up completely during runs?
Something cost you HP. I would expect a higher number.

here is my dyno sheet
all runs were comp2 tune 47-49 psi on the street itll hit 51
highest egt was 1385
blue 9* 100% 2200 stretch 482.74 1047.11
green 7* 100% 2200 stretch 472.92 1030.90
red 9* 100% 2200 stretch on pl8 478.66 1003.97
with 2000 stretch i lost 3hp and 17ft lbs 479.77 1030.55
with 10* 2200 stretch i lost 28ft lbs 482.87 1019.11

Remember, these numbers are corrected numbers. Actual hp# is 552hp. I have a list of the settings used below the graph.

QUICK PONIES
Did you know it’s also possible to display higher than actual power readings? If you tell the dyno operator that you just want to see how much horsepower and torque your bike is putting out, you can bet most aren’t going to stop with one run, with a result of 68.6 hp, for example. Especially if you mention you had it on another dyno, which you thought was reading low. They’ll likely keep doing runs until they hit 74.8 hp, right? But what if they (or you) wanted a little higher number? That brings us to correction factors and smoothing.
All dyno measurements are affected by air density. Cool, dry air allows an engine to generate more power than hot, moist (humid) air, which is less dense. If dyno software didn’t correct for temperature and humidity, we could never get consistent readings, even on one dyno in a fixed location. To compensate for these variables, modern dynos have hardware modules, which measure temperature, humidity, and barometric pressure automatically. Truth is, all dyno software has built-in correction factors, but it’s the operator who gets to select which one is applied.
Dynojet’s latest software package (WINPEP7) offers the following correction factors: SAE, STD, DIN, EEC, JIS, and UNCORRECTED. SAE and STD are US standards, whereas DIN and EEC are European, and JIS is Japanese. Each one figures in temperature, humidity, and barometric pressure a little differently. Uncorrected means no correction is made to the raw measured data. According to Dynojet, SAE is the proper factor for tests done in the US, and it’s the one I use exclusively. But as you can see from the chart titled Dyno Correction Factors where I applied the other factors to the Road King tests, it also gives the lowest readings. (Uncorrected gave even lower readings because I did the runs on a warm, humid morning.)

Not sure about smoke, couldn't see anything during the runs. Lots of smoke, but then darkness.
