Had my 2004 Ultra dyno on 20th of August, 2008

My bike has the Stage 1
SE Slipons
Arlean Ness Breather
Power Commander

before dyno 65.94 Power
78.45 Torque

After dyno 71.63 Power
81.30 Torque

Took the bike to Milwaukee pullin a trailer average mileage was around 40 mpg, the tank I used riding around Milwaukee (R U sitting down) I got 60 mpg, checked it three times to make sure. Out of 12 tanks of gas the best I got was 60 mpg (not pullin the trailer) and the worst was 20 mpg (pullin the trailer).. Had mine done at the Stealer in Topeka, Knasas,,, waiting to see what I get around town. I could see the difference between putting on the PC three years ago and having it Dynoed this year.. Have a qualified person put on the Power Commander when u get it Dynoed, they can tune it better than doing it by yourself on your home laptop...
 
I have an 08 FLHTC stage 1 air filter and ecm,power commander 111 usb, vance and hines big radius pipes. Just had bike dynotuned, can send map to anyone interested
 
I've attached the best chart for my road king 103" with screamin eagle performance heads, se251 cams, bassani roadrage 2 into 1 exhaust...in a nutshell, the important thing to look at on a bagger dyno chart is the torque curve...see how this one is a gentle curve?...if a motor is making 75 to 90% of it's peak torque by 2500 rpm it's a good one
 
nothing wrong with the build or tune...the fatcat quiet baffle might improve torque a little....like I said before, your compression is low for that cam...going to 95" would improve it greatly and can be done for $150 bore job and $150 pistons
 
Just got my bike back with a stage one:
Before: 66.23hp 80.92 torque
After: 75.11hp 94.06 torque

The shop said if I was at sea level(presently at 5000ft) these numbers could be about 10% higher. Maybe next summer I will find out how my bike preformes at sea level on one of my trips.
