added this video to the 1st post...
Going to go do a 115 mi run up I5 in an hour or so... average runs have been 20.2~20.4 mpg on this run during testing with 1 run at 21.15... I dont buy that one however, I think there was an issue with the fuel level in the tank, maybe an air pocket...??? I can say though that doing 2 cheap & dirty changes made the low end noticeably stronger... blocking the air to the airbox from the front area forcing it to draw in warmer engine compartment air and then (looking at effects of controlling airbox airflow) blocking some of the opening to the airbox (I'm missing the foam and have a broken airbox pin so it is loose in there).
I still think that bumping up the IAT's to around 80~90*f will yield some gains. Came up with a potentially cheap easy way of moving warmer air into the box in a controlled manner. Wifes gone this weekend so maybe I can bang that out??? hahaha
