Default New Dyno tune today!

Firstly, last June I hauled my AF Green XC to Iowa to see Rylan and have him install the VM1DR cams, Timing wheel, VFC3, and dyno tune it. Can't say I wasn't happy, but after today, WOW!!!

I started out not completely bone stock, but just o2's pulled, D&D exhaust and Lloydz filter.

Pre Work: 80.98 HP / 100.75 Lb Ft Torque
Post Work: 101.35 HP / 109.79 Lb Ft Torque



And now, with the only difference being the PCV:

119.5 HP / 127 Ft Lbs Torque


2013 Anti-Freeze Green XC
Vance & Hines Slip On's
Lloyd's VM1-DR Cams & Timing Wheel
Lloydz Air Filter, Lloydz Rev-Extend
BadBoy Horn, PCV
Gustafsson +4 Windscreen
Picasso Nano PN2.350D Amp
Audison Voce' AV X6.5 Speakers
HMD520 Gorilla Bagger Bars

2010 XC 116 Big Bore - Gone
2006 Hammer - Gone

How much of those different numbers should be attributed to the difference of the dynos? I know the dyno in some shops give very optimistic readings and some return very conservative numbers.

Not sure how a PCV can add 18hp and 18ft/.bs of torque. Smooth out the power delivery, you bet, all day long. Maybe resulting in a +2 gain. But add 18hp and 18ft.lbs/torque, I don't think so.

The end result is you seem to have a very well running motorcycle which is the best end result possible. Congratulations for that!

All the best,

From what I've read on this forum Rylan's dyno seems to be more conservative than some of the others.

Again, Bingo, but the A/F ratio is a lot more consistent.

Unless the before/after was done on the same dyno...
The best comparison would be same dyno/same day, but that is not always possible with engine builds that take time. You'll have to settle for same dyno/same correction factor. As long as the temp is between 65 and 90 degrees it'll be accurate enough.

My last tune gained me 4 HP. Nothing changed as far as components, just the difference between the tune Lloyd put on it and the tune Kyle put on it. SAME DYNO.
122 HP and 38 mpg
vs
126 HP and 45 mpg
That tune paid for itself in fuel saving alone.

Good morning sir, I have to ask, what was done differently in the new tune that gave you such a dramatic difference with out changing a single component? That's an impressive find of 4 hp and the fuel savings ? wow!

Good morning. The quick easy answer is it was RICH AS FUCK. The drivability is much improved as well. The bike is not nearly as 'abrupt' on and off the throttle and will actually go slow in 1st gear.

now what you need to do is upload the map from your PC-V to your computer and share it with others to try in their machines.

Looks like a good tune. Looks like it may be a solid runner.

Although I am certainly happy with my bikes performance and Kyle's tune my bike seems to have the same behavior as yours did. I have low speed abrupt throttle for sure but cant say it's rich. I guess only another Dyno session will tell other than pulling the plugs.

What made you decide to re-tune? Did your bike just start to show signs of loosing its tune or did it run like this always from the last tune. You got me wondering HC .

One difference may very well be attributed to the the fact it was very humid when Rylan did the initial dyno.
