I ate Chick-Fil-A so I'm good

Some more observations from commuting with the Cold Ram Air. IAT stays about 10 degrees above ambiant, I believe from heat soak because of the full grill block. Temps were 35-37 degrees today and the IAT was around 45 degrees. When I had to idle in ttraffic for a while the IAT rose to 55 then dropped back down to 45 when speeds picked up. While the Cold Ram Air didn't seem to hurt FE much, if at all, in the 50-60 degree temps, it seems to have a negative impact in the the 35 degree temps. Although this is all subjective right now, it "seems" to be a small negative impact. The negative impact could solely be the cold temps. MPG going to work today was 43.4, coming home was 39.2. Reallllly bad traffic tonight, but it should have been 40-41 and this morning should have been 44-45. At least that's what I'm used to seeing with the Mild HAI with IAT's in the 80-100 degree range. Can't wait to get the Wild HAI hooked up! The Heater Core I got is a bit bigger than I thought, it ought to put out plenty of heat

At 50 mph with a TPS of 21 (Idle is 17, WOT is 94):

MAF is reading around 8.00
Ignition advance is 38. This is max for my PCM.
GPH during these conditions is around 0.90
Instant MPG is around 57

(At least this is what my colesterol soaked mind remembers right now)
