Dond need to hcange the set up if you just have a slip on. if you get the full exhaust or an intake, than yes. just throw the slip on and go ride.

True you don't need a fuel programmer until you upgrade your intake tube....

More air = more fuel...!

With that said...you can get a better throttle response with the optimizer & air box lid off for now...!

Set it to stock...thus green 1.5-yellow 3.5- red 2 and go from there...!!!

dust devil is right.

mine came 1.5, 4, 2 preset for airbox lid removed and exhaust though.

when you upgrade to a fci or cfm intake 3.5, 5.5, 5 should be pretty close for the big three. up or down either way from their to get it fine tuned.

the settings we mentioned will work for both. exhaust and k&N filter airbox lid removed just plug it in and run the preset settings.

ltr intake tube should be around the higher settings I mentioned.
