true, i thought about that as well, but my fuel mileage has only varied 1~1.5 mpg from winter to summer. But i can tell the grill block difference, because it doesn't downshift as often or as early on my trip. Plus drafting... it won't downshift going up hill, it's great.
Ohh and FX2.3, do you have a E-fan? if not, get the one from Jusnes [?] modified. I have that and when i put it on last year it up'd me 2 mpg in town
