Sometimes, you have to accept that you can't be the only voice of reason on a topic. Forums teaches us that a jiffy...some comments here about changing the air box, well some people just like to think they know what they are talking about.
Ok, I wrote "coerced", as in "pressured" to buy further components by typical retailers exploiting one's odd fear of performance loss, regardless of these components being required or not. I don't need to know the exact requirements to make my point, I just know many retailers will screw you at any opportunity...
If the remap is not involving further changes, that's REALLY nice. But when a vast majority of riders don't see a real problem with the versys 650 rpms, the opinion of leaving the ECU as it is deserves some support to oppose the advertising you just did.
If guys like you and me can remain fairly unbiased (and it's hard, I know), then the forums has better value. I think we can agree on an objective truth and only then lay our preferences.
