Well it is definitely easy to get confused by all the hyperbole spouted by everyone of the oil makers and air cleaner makers. There is "no truth in advertising" with most products. Up until the last decade or so you could not say it in an ad unless you could prove it was true. Now it is just anything goes and nothing can be taken literally, unless you read it on the internet of course.

 

yeah, it seems like who you ask and depending what time the sun is overhead on any given day the answers (opinions) change..keep in mind that the K&N has twice the surface area and is much more porous than the smaller OEM paper filter so naturally it's going to allow more air in..imo if you're messing around altering stuff just do a proper stage 1 and be done with it..engine is better off anyway and get some noticeable improvements

 

You're right about who you ask about things but when you start asking the people the manufacture motorcycles and people that tune them for a living the answers are more credible and have substance around them over internet "opinions" and hearsay. It's kinda like the arguments that an auto tune is as good as a dyno tune by someone that knows what they are doing. In certain circumstances it may be close with a stage one bike but going much beyond that with the motor requires more than a VE table adjustment.

 

yeah, and I certainly ain't knowledgeable enough to dispute some things so I just usually defer to the manufacturers recommendations, which has never steered me wrong..I don't like to fuss over stuff like this

 

Understood. If you take the time to read through the overwhelming settings that are available settings that are modifiable with a tuner like the power vision you will be even more inclined to leave it to people that do the stuff for a living not fully understanding how some settings affect others. For $250 I will play it safe for now and hand it off to someone that knows what they are doing when the warranty expires.

 

I bought the SEPST and decided not to muck with it myself, paid our highly reputable tuner at our dealership to dyno tune it, there's zero chance I would have gotten the great results I did if I screwed around with it
