Just to make sure you understand, I test rode a Aprilia Tuono today - after I got back on our mighty f800gs it felt as if the engine is broken and they don't come with brakes ... Wow - first time I ever rode with a quickshifter - crazy.

Any idea what to expect?

I do have a few ideas. When you speak to mx, or sm racers or their tuners, they all ride different equipment, but all agree, that their the hardest thing to to is to ride their FI bikes from the trailer to the track. That is the first thing I expect to change..... The off idle monkey hopping throttle control. It is a well known issue, and not just on the 8GS. The other thing is overall throttle control improvement. Once you ride a well fueled bike like you just did, or my SSW tuned 55 rwhp Suz. DRZ..... then you know how crisp and clean the throttle response can be, but epa keeps a lid on the stock mapping. Like carbed bikes that comes with a stock diaphragm carb, many change to aftermarket carbs which has accelerator pumps, to aid in acceleration. Same can be said with the stock maps, they are choked as well, due to epa. So the overall throttle response will be a lot better. Those truley is the main reasons that I do this, as the 8gs has plenty power in the dirt. BUT.... overall HP, and Torque will also increase, as the CAT'less headers are installed along with the tune. I am expecting something along 5-8 HP increase. But that will not be as evident as the other two benefits. A third smaller one is an overall smoothing of the power band, as many of the "dead spots" will be minimized. Currently the 8GS has several "dead spots" and they will be minimized, if possible. I do not expect that fuel mileage will decrease by much, if any. You see, it basically takes so much power to move the bike, in acceleration, etc..... providing the tune is done right. But just in case..... it can be switched off. Finally.... I am just flat curious, as I have a few predicaments.... one I have always suspected that the snorkels are too small. I know not many agrees, but imho, that is the case, so we will dyno with and without the airbox cover installed. This will all be backed up with Dyno graphs, so The results are out of my hands, and non biased. Just two more days.....

Yay, a little less than we were expecting, tough at what altitude are you now?

Also proofs!

Headers and my pipe..... only picked up 0.5 hp to 72.5......
Dj power commander 5 with auto tune .... 74 hp...... not a huge gain... but the curve is smoother and no off idle hop.
Testing done at 5500 feet in Denver, colorado

He he....yes. the a/f ratio is now 13.2...... before it was from 14, 7 to almost 18..... off idle is fixed.....and now time to ride it.

Oooohhhhh my good god...... this thing is sick. No more throttle hop of idle. For the first time can I idle it in first going through dirt..... all day long..... just mega low speed control. More to come.

Had very stiff head winds going up north to the KOA, but once heading west at 55 mph, I was still getting 55-65 mpg. So cautiously optimistic....that fuel mileage has not suffered. Anyway to avoid any more suspension..... here is the proof....
Blue.... 100% stock.....
Red......My own CF muffler ( open pipe with no restriction)
Green...Arrow headers, and my pipe.
Purple..Arrow headers, My CF pipe,DJ PC-5, with auto tune, base map with dyno tweeking with a/f of 13.2


Although not depicted here, we saw as high as 18 a/f ratio off idle.... and perhaps even higher. That is the reason for the kengaroo hopp off idle. Test riding it on a dirt track afterwards...... I was able to put put in idle in first, and when going over the small jumps ( 3-4 feet) I just bleeped the throttle while standing, and the bike smoothly clawed it's way up.... No clutch.... Try that on a stocker.......
I am at a koa with bad internet..... But I have pictures and videoes of the whole ordeal....Including the dyno runs. As I get a better connection, I will up load them. Eddie mentioned that with the almost new K-60 back he was assured that there was alot of slippage, and the numbers are actually higher. I could hear the bike snap faster on the last few runs.
Here are a few teasers though....On the dyno for the runs...



Ryan left, and Eddie on the right.....After a fantastic job.



Enjoy

Pictures...

Driving up in the morning...



In the ER...



On the dyno with the only way the stock muffler would fit........



Second run.....



Back in the ER ready for headers, and the electronic goodies....



Access to the Injectors, as the pc-5 injects itself between the stock ecu, and the injectors...




Goodies....




Temp switch to disengage the at, in case it now was a fuel hog, which it did not appear to be...



Header access.....





Back on the dyno....
