Looks Good!
I blocked off some cold air entry points thereby raising the IATs accross the board. With a slight change in weather (Temps up 8-10° and RH down to 25-40%) and this mod, it looks like I have about 5% savings on same weekly trip cycle. Judged by ScanGuage and Fill Data, both in perfect agreement.
My IATs are nowhere near 140° however. Maybe consider backing the IATs off by moving your intake a few inches back of the manifold at a time.
I'd think on startup/early ops, the 140° may be very beneficial, but as FWT get normalized around 185°, I'd say a few degrees less WAI will still provide same FE increases.
I found a spot in my parking garage, that if I back in to, the sun will only shine on my hood for about 2-3 hours prior to the afternoon drive home. I'm anxious to see if the additional underhood heat load will help on getting the FWT and IAT up earlier on the trip home.
