I take most of what I hear with a grain of salt, (just like I wouldn't expect you to believe evrything I say here just because I say it), I only go by what I have experienced on a dyno that I was running. And I will say that I have ran bikes without fuel management running well into the 15.xx:1 A/F, we've had customers come in with running issues, after installing stage I kits themselves, so I put the bike on the dyno, hook it up and record some wide open runs and set the load control on the dyno and run the bike through cruising speeds and watch the air fuel. The bikes I am referring to are completely stock mapped with either full exhaust or slip ons and stage I or big sucker type filters. Like I said, this is what I experience on our dyno with me running it. That's what I go off of. I don't rely on what i read in a magazine because, IMO, an article in a magazine could be nothing more than an advertisment. There are alot of exhaust and air cleaner manufactureres out there that want people to believe that they will be fine without adding a tuner of some sort. They want people to believe this because for alot of people, adding the cost of a tuner and a dyno tue to the cost of a simple stage I might be the deal breaker for many.
As for the "tuner" you are referring to, I can't speak for him and what he has witnessed, I have never heard of stock o2 sensors adjusting 6% +or - 2. (not that it might not be true, I juts have never heard it). But look at it this way, if it is true, an open filiment (big sucker type) air cleaner will flow more than 6% more air than a stock filter. So even that logic doesn't hold water with me.

Bunch of dentists, lawyers and wanna be ex 'drag racers' on this site. Good for them... none can see the truth if you hit them over the head with it and they all gang up on the 'bully'.

Ok , think about this for a minute, Harley tells me "you dont have to remap if you just put on slip on mufflers ..... but if you put on an aftermarket breather then you have to remap.... "because you are getting more air into the engine" so they are basically saying that their stock filter design is so poor that it is actually restricting the amount of air your engine can get through it ....if it is "getting more" air with another breather .... now I have been building drag racing engines for over 30 years and have proven over and over again that with or without an air filter on it , no horsepower is gained because basically an engine is only capable of inhaling so many Cubic feet of air per minute through the same carb/injector ..period...if the filter design is good to start with................... so unless Harleys design is a total piece of crap and is restricting the engine.......in the first place the engine is not getting any more "air into it " with a stage 1 breather or similar breather or no breather at all............So why do they tell you that you need a remap? more money for them ???

From what I'm reading in here I can just slap in a K&N and I'll be ok right? I put aftermarket baffles and a K&N on my previous bike which was a carb'ed Honda and didn't have to worry about the air fuel mixture settings. Until I rejetted the carb. Again sorry for the stupidity. Still learning the Harley. Thanks in advance.
If you rejetted your bike, you did change the A/F ratio. Look at the fuel injection A/F ratio as the same as rejetting a carbed bike, just cost more...

With all due respect, not everybody on here want's a touring bike with a 120R in it.

No it wasn't mine. Here is before and after. I will also show another that is the difference between a download vs a tune. These sheets only show wot. The big difference is how much better the bike runs where you actually ride it. Anyone that has never ridden a properly tuned bike doesn't know what they are missing.
