Yeah man, not to be a dick but chris is not a tune master for one thing, he is kinda new to it, sure he is doing the damn thing but he is riding his youtube fame to do more than he knows about in my opinion, I saw the vid where he got over 200 hp on our bikes with just a flash etc, but it was all dyno stuff going only for max hp numbers and not even taking into account longevity rideability or streetability and really the zx is mostly an afterthought for him. like i said if you drag race, then maybe but otherwise hell no, graves for a canned tune any day, but for around 400 you can have a tune setup on bike, for under 7 you have wideband, logging, autotune, full control of everything about your bike, easily read and clear codes, on line email and phone support, maps that are shared, a chance to learn and really since each bike is different a tune that fits your riding and your bike and its setup to a t, worth every single penny, first thing i did to my bike this time, then the saddleman seat but first is woolich with logbox and wideband. worth it and some, if you know anyone else with a similar gen zx you can do their bike for 100 bucks fyi or charge them a lil, but you can disable all fi codes, change shift delays rpm limit, fuel ratios and all sorts of shit. and can always set it back to to stock for warranty or whatever else may make you do some crazy shit like that, still, just a thought, pony up for a woolich setup start with the basic with on bike harness and then upgrade to logbox when you dont mind spending the extra, or dont but man, you are missing out and dealing with dumb shit if you dont
