I was shocked when I first rode the Fatboy S. I think by changing the gearing would wake it up.
That surprises me. I have no issues with take-off. According to my G Tech Pro yesterday, my 0-60 times were between 4.4 and 4.6 seconds. That's not lightning quick, but that's not too shabby either. I use the G Tech Pro in my C6- GS at the track and it is very close to actual track times.

0 to 60 in 4.4 to 4.6 is slow. If that is your current time, you will see a big improvement with regearing.

Jim, It runs just fine for me. I do a lot of HWY riding (I live in Texas, it's a long way to anywhere) I could improve on that time some, but those times are just a normal take-off and then roll hard on the throttle at about 7-10 MPH. I love the way it runs and I am done with performance mods. When I have a real "Need for Speed" I climb in my 856 RWHP SC C6 and go play.

I don't have the skill level on a MC that gives me a comfort zone for really pushing the max out of one and at my age it's not going to get any better. I love that 2sd-3rd-4th gear roll on the throttle that this SlimS gives me. To each their own

Those are good numbers. I guess that aftermarket AC does make a difference. Mine only made 93.07 hp @ 4.89 and 115.31 for torque @ 3.55

With the Slim S being such a light weight bike (for a Harley...LOL) I asked Ed to tune for a broader TQ curve instead of trying to hit peak #'s. He tuned it first for peak #'s and got 96.9 HP and 116.1 TQ. He then re-tuned it for a little broader TQ curve and optimum throttle response.

Final tune is 95.3 HP @ 5100 RPM and 113.7 TQ @ 3772 RPM

100 LB's of TQ from about 2250 RPM to to 5000 RPM

110 LB's of TQ from about 2750 RPM to 4300 RPM

From 2500 RPM to 5500 RPM the TQ averages 106.76 LB's

I absolutely love the way this thing pulls from Idle to about 5000 RPM. Spinning a HD with the 255 cams much past 5K RPM is just unnecessary wear and tear on your motor.

Z, those are just #'s and their extremely close, no way you could feel the difference. You have a great tune with a very flat TQ curve. I changed out my AC for cosmetic reasons, not to gain power. ( I still have to powder coat that screen basket Black)What dyno charts don't tell you is throttle response. I wish there was some way of charting throttle response. IMO...for a HD, throttle response is what makes me smile

Yeah, the response time is incredible and mine really gets with it when asked!
