After yesterday installing my catless oem headers and UNI air intake filters, today went to get dynoed and tuned. I was waiting for a time that I could get all my parts installed. I also have modified my airbox by adding some of the UNI vents and heat taped and have the Power Commander Fuel Controller (PCFC.)
Went to Sabin Performance in Dallas, Texas. Owned by former racer Jim Sabin. He's the one who dynoed and tuned my bike. Turns out I know him (sort of) through a couple of friends who all but insisted I take my bike to him. And he got me in on very short notice. He also makes dyno and tuning a priority. He did not reflash my ECU. Just made a new fuel map based on the dyno results. The pictures posted below are dyno runs before any tuning was completed and the runs were done in Touring mode. He tuned the bike on Sport mode. I have to wait to get the final tuned results via email and I'll post them. Most of the tuning was actually leaning out the afr (air fuel ratios) Believe it or not the bike was running a little rich! I was using a fuel map from the power commander website and that fuel map was built upon just an aftermarket muffler.
As far as riding the bike after Tuning.....HAVE MERCY!
The bike rides incredible! I'm going to getting better gas mileage as well! Final after tuning hp was 96.66 hp. I've done a lot of reading on this site of others posting their results of reflashes and other modifications. I didn't always quite understand what some meant based on descriptions. But now I understand many more things people are describing. I'll try my best in my words. In a nutshell, yes the bike feels like it has way more horsepower and pull. Yes, less engine braking. But the pull is not like a jerky snap your neck pull. It's very refined and just keeps pulling! It just feels stronger. He did probably about 20 or more runs on the dyno and told me a lot of info. in a short amount of time so I'll do my best in that department as well.
The bike does what I tell it. I always thought it did before. I think a lot of the things is that in riding, I was adjusting to the bike and its nuances. I guess I've always kind of ridden this way on any bike. Now after the tuning....I give it throttle and it goes according to what I give it! Took me a little riding around to get used to the power and the way it rides now. Now that I understand it....It is just a great ride! I'm also probably noticing a little butt dyno affect because cutting out the cat drop some weight on the bike. I also, don't have my panniers or my crash bars on the bike and I normally ride with them on.
Sorry about the pictures, I took the pictures with my phone.

I know these are famous last words...but I'm done as far as engine and performance changes for the forseeable future. I just wanted my bike running as efficiently as possible. Before adding any more power; I need to get my rider skills up to utilize the power.

Those dyno runs show the dip that everybody talks about.

Can't tell for sure, but I think the graph at the bottom with a big dip may be the graph of the A?F ratio. If is a graph of HP, it goes way up right at WFO.

The graphs posted show speed at the bottom, in the top graph the blue line is most likely done in a different gear than the green and red ones.

The bottom graph shows air/fuel ratio. The dashed straight line is at about 13.2.

Attached is one from my bike.

For the BHP/TQ, is there a graph with rpms? Is this at the rear wheel?
Generally you get RPM on car dynos as they can lift the bonnet to get at the wires to pick up the rpm's
RPM pick up is harder to do in a bike as you have to lift the tank and get under the airbox and that is time. and $$$

Speed or Rpm does not matter they are relative across the x-axis on the scale.

Umm... yes this would be a dyno of the rear wheel.

Cars differentiate, why wouldn't motorcycles? And if I was going to spend the time and money to dyno my bike, I would also like to know at what RPMs my bike is making what BHP/TQ. Just sayin'.
