Will i need a fuel porgrammer for a two brothers dual?

[CantWalk:)]

When I bought my Spyder it came with an uninstalled two brothers dual exhaust. Will I need to get a fuel programmer to use it if I install it? If so any recommendations on a programmer?

The rule of thumb is typically one breathing mod, no fuel control needed. The stock ECU should handle it within it's tolerance. But you'll likely be popping when the throttle slams shut but every bike is a little different.

Not 100% needed but it sure helps.

YES SIR you will need one.

It is not required, but if you do get a programmer, go with 2 brothers. They already have a preprogrammed mapping in the Juice Box Pro for a setup with a stock intake and the dual tb exhaust. SNY is right though, the juice box will cease the backfires. I had a lot of backfiring when I had just my single slip on, I have since installed the Kewlmetal airbox and a juice box pro, and Viola, no more back fires, but it really doesn't like to have the clutch being engaged when rolling cold.

I did the same.. No box .. A hindle + K&N + O2 mod. They all work great together.. No backfiring..

Sure spyder will run without a fuel mod but it will be starving for fuel.
When I turn mine off and run with just o2 mod, spyder begs for for more fuel outside of closed loop.
I guess it would not matter if you are going accelerate slowly every time but...
I think a fuel mod will do a lot of good. 265 bucks for jb pro on eBay.

Check you O2 mod.. Begging for fuel is not a good thing..
