Cams - Pipes - And Tuners. Questions
Hope everyone is having a great Monday! I have a question of you tuner folks. I have a 2008 Dyna FXDF. It is used and has 30 K on it. It's one owner. He bought from dealer, and before delivery they added a HD tear-drop style breather and some SE slip-ons and told him they did a "Stage One" tune. If that is so or not is not known, but I suspect they did some small mods to the tune for the increased breathing.
He drove it home and with a few days bought a Vance-Hines Pro-Pipe with stock baffle (not the performance or the quiet one) and installed. Pretty much all that has been done to date. Has narrow band o2 sensors. The bike, at 96 inch, runs pretty nice and torque-y and has decent sound. But the limitations of the stock cam intake profile prevent the pipe from helping draw much air into the unit, and thus I am swapping them out. I chose S&S 583 based on the bike's weight and my riding style. From what I see they are pretty much the best choice I could find for this street bike and what I am hoping to get from it.
As far as the main question - tuning. I am familiar with the SERT which I have used on earlier models with no o2 sensors and it offers everything needed for those. I have a NOS SEPST 32019-08A BLACK here that NIB and unmarried. I've not used those. My research suggests that the number of canned maps (I am nowhere near any dyno shop) is limited for this combo in the HD SEPST. Not that I won't find a use for that, but I was also considering the purchase of an FP3. Both seem to have an "auto-tune" (I think the FP3 more-so) and wonder what you folks think of my chances of a good non-dyno tune from the SESPT and it's data collection and canned maps. Or do you tuners think the FP3 is a better option.
I'm not that great of a tuner. I know the fundamentals and can read maps and stuff from messing with the SERT and just reading posts here and elsewhere.
All ideas are appreciated. If you think I can use the HD tuner and save myself some money that would be nice.
Thanks in advance for suggestions and ideas.
