Very cool. Since you removed your stock mirrors I think there could be some benefit as well from a lowered windscreen such as the stock screen on the base SX.
I was thinking of trying it anyway, I get some decent buffeting off the stock h2 sx se shield at higher speeds

Yes, even when you disable the speed limiter in the ECU, the display maxes out at 300 kph. That would be 186 mph but who's going to argue 186 or 189 when you're doing 203 mph?

It's amazing how fast you can go when you take your time.

Took my bike out for the first time with the intercooler and David's tune done on his dyno to see how it would run. The weather was quite nice around 72 degrees down here in Florida. I was running 93 octane, mirrors on, newish tire, with the rear lowered about one and half inches and the front strapped down but not extremely tight and a 19T in front and stock 44 in rear. I got behind the windscreen but not really laying on the tank. I'm 160lbs and have some fairly heavy gear as I wear full leathers and an air bag vest so not ultra light. Also stock front fender. I wasn't on the greatest track and started running out of room but not sure there was a whole lot left. I wasn't looking real close but I probably was at around 13,000rpm indicated so there was another 1,000rpm to limiter which I don't believe I was going to hit. So 194mph on GPS. So those who think they are going to hit 200 on this bike need to have more than just get a tune and go out. The highest intake temp I saw was 167 with the intercooler. I was hoping for more but it is what it is. I do have an e85 tune but David said that is only around 10hp more so that's not going to do it. Apparently the aeros on this bike suck because I could run 205 in the mile with my NA ZX14R all day long and my ZX14R turbo is a whole other animal altogether, that bike is still spinning the tire at over 200mph lol.

take the mirrors off and the air bag suit and i bet that is 3-4 mph

any thing causing disturbances in the air at that speed is big, the air bag suit flapping on your back would be like a little parachute almost

Believe it or not I think the air bag vest calms things down at high speeds. I and some of my riding friends have experienced an aero effect wherein when you are tucked in at high speeds 180+ you feel this pounding on your back from the wind. With the vest I no longer get this so I'm not sure what is happening but it was very uncomfortable with the pounding. Yes I'm sure you are right about the mirrors but I won't ride without them so I guess 194 is where she will sit until I can get a longer smoother stretch to eke out a little more. lol

i rode to the place I did my run with a bar end mirror then pulled over and removed it
