I'm lookin at getting a new air intake system. the install of the system is easy enough, but unclear about having to modify the fuel control. Ive heard from some that you dont need to screw with the fuel unless you swap out the exhaust. but heard from others that you need to modify if you get a new air cleaner. can any body clear this up??

you only need it if you do both. one will restrict the other take them both out and theres no restriction. If you change both you'll need either a dynojet powercommander or a cobra system to adjust the air/fuel system for example. Even drilling holes in the stock exhaust would be considered changing the exhaust
Sorry XPS I will have to disagree with you. I changed my air intake on my other bike and kept the factory exhaust and ended up buying a fuel commander a couple of months later. I lost 10+ % gas mileage and the end of my pipes started turning black because I was burning so rich. Took off the air intake to see what would happen and gas mileage went back up and tail pipes were fine. Only way to use my air intake was to get a fuel commander.
ALL DEPENDS ON HOW MUCH MONEY YOU WANT TO SPEND AND HOW MUCH CONTROL YOU WANT OVER THE ADJUSTMENTS. Cobra has this new power commander that sounds great, but so does the price. Some you can get for as little as $100, but there is only primitive adjustments that can be made. I had and will be getting again the Vance and Hines Fuel Pak. About $200 to $250 control over 30 plus points, from negative to positive value positioning. Worked great for me and the price was reasonable.

what bike did you have the FUELPACK on?MY said:
STRYKERAF: They are direct plug in if you order the one for the Stryker. Just unplug the old and plug in the new. The difficulty is running the wires so they are hidden. Your going to place the device under your seat and the fish the wires through. Most times you remove the gas tank, but I'd be nervous with this bike because of past posts I've read on this forum. There seems to be a problem with when the tank goes back a screw goes through the tank and makes a hole. I'll be leaving it to my service shop.strykeraf said:
Is there an unspoken man law against mixing companies?? ??? ??? say i got a vance and hines exhaust system with a la choppers air intake, and a cobra fuel management system?? i dont think it would cause any problems..besides maybe them all fitting together.

Some companies will have everything set up to work together,intake,pipe, and a program allready setup. If you go with different companies you may have to do more tuning. Or spend a little more and get the self adjusting programmer. Thats what I'm thinkin, the difference in price is probably less than payin for a dyno run?

mix and match... make it your own 
I TOTALLY AGREE WITH KCL, BUY WHAT YOU LIKE AND PUT IT ON. Of course manufacturers want you to stick to their brand for everything and will tell you it makes a difference, but I think it is so little its unmeasurable. The Vance and Hines Fuel Pak lets you pick the exhaust and air intake and then gives you the numbers to put in. http://www.fuelpakfi.com/
One thing you have to remember is that this bike does have an 02 sensor so the computer can adjust. Gaurantee you if you go too far out either rich or lean, the check engine light will come on. Yeah, if you go too drastic and do both intake and exhaust a programmer is going to be needed. Many Older fuel injected bikes have no 02 and not as much technology.
