Default slip ons with EFI ???

I just put on my new V&H Oval slip ons..... Sounds great and runs good too, just a few gurgles when slowing down.
I havent done the intake or any downloads. I read here before that this shouldnt cause any trouble. But I would like to hear it again for my piece of mind.
I have a Big sucker sitting in the garage(not on the bike yet) and a DFO on order. I dont need to park it until the DFO comes do I?[&:]

You should be OK until you change the air intake....then you will be running leaner.

Your exhaust is fine as long as you don't install the breather. That will lean your bike way out and you stand a chance of burning a valve. You'll need an aftermarket ignition system or Harley download for your ECM. I like the Vance and Hnies slips-ons as well. Good luck.

Thanks guys that makes me feel better. Question though, once I install the DFO and intake will I still need to do a stage one flash of the ECM?

Contrary to many beliefs, you do not need to reflash when using the DFO/TFI. The only benefit to the download (reflash) would be a higher rev limit, which on your bike would only spin the motor over higher (not a good thing with a TC) without any real benefit because you are already past the power band of the stock cam. Only other "benefit" of the reflash is if the DFO takes a dump, you'll still get a bit more fuel to the engine. The DFO is also more adjustable ( range wise) without the download and can be dialed in better. To date, I've never heard of a DFO taking a dump.

Thanks for the help. When I get the DFO installed is it a pretty straight forward adjustment procedure?

I too, would like to know what DFO stands for, (I'm assuming that its an acronym ) It's too bad that some who have been here longer feel that it would be troublesome to be helpfull but instead, more eager to make reference to past discussion.
