Looks good, I put one on my vert, to be honest I didn't notice any real gains other than Tair was, as you say, more stable. I did find that my Tair was/is a lot lower than what you are getting. On wot mine is quite comfortably sat at around 20, on a warm day, in town about 35, winter is obviously a lit better, what kind of intake are you using ? If it's standard you should be getting lower than you are stating
