I have a 2008 Vegas Low (closed loop fuel) with D&D slip ons 02's
unplugged with stock map and stock airbox and filier. The bike runs fine now except for some popping which is normal for after masket exhaust. If anything it is running a little rich as I can see some black on the inside of the pipes. I have decided to go with as S&S intake. Originally I did not want a fuel tuner but I am now unsure. Have read some people are having problems with the S&S maps while others seem to love them? Option 1 Is have dealer install S&S intake and download S&S map at a cost of $500. Option 2 Get S&S intake and Lloydz VFC 111 Fuel tuner for $575 and do the install myself. Really not planning any internal mods at this point. I guess I am wondering which option is best for bike. Performance and driveability. What do you recommend? Thanks

If you look inside a thousand bikes exhaust there all going to be black.
What are you getting for mileage? that will tell you if your reach or lean.

Do your air cleaner mods and ride it for a thousand miles and then think about a tuner you might not need one.

visionjohnny thanks for the response. Before adding the D&D's and unplugging the 02's I was getting around 42-43 mpg. My milage has dropped to 38-39 mpg but that may be the way I ride it? Twist the throtle a little more now. Everyone I have talked to said that if I change the exhaust and intake I would at least need a map Stage 1 or something other than the stock map? Are you saying the bike may run fine without any kind of map or tune? I do not want to risk running to lean and damage the motor.

I've heard so much bad stuff about the S&S map download, I'd be pretty leary of it. Unplugging your O2 sensor has already put your bike in a richer running condition than factory (which is good as the factory setting is way too lean) which accounts for your mileage difference. I would guess the S&S is going to lean it out a bit from where you're running now as you'll be getting more air but the same fuel load. If that makes you nervous then you might want to opt for the fuel controller so you can have some control over it.

Currently, the bike is not "TUNED". You have done things to richen the mixture, but to what? You have no way to know.

If you did the S&S airbox and S&S download it would be very close.... but it is still not "TUNED".

There is no substitute for tuning. Either it is or it isn't.

Thanks DunedinDragon and half crazy, sounds like you both would favor the VFC 111 tuner for the best results. I think I am leaning that way. Any other opinions?

I didn't say that. If it was mine it would have a Power Commander on it and a good dyno tune by someone with talent.

Drivability is seamless, gas mileage is always over 45 mpg. Worth every penny. The tune will pay for itself in what I save on fuel.

Thanks for clearing that up for me half crazy. Funny, my ex wives said I never understood them either!
