I am getting 8.8-9.0 MPG on my newly converted HO. Whats the deal? I went through a 1/2 tank of gas in like 2 days. Exhaust is still just off H-pipe but everything else is right. I haven't had my foot in it either b/c i am breaking it in.

I know how you feel mang....... I just put the 4bbl on mine and I go through a tank real quick if I'm into it.
Could it be that you have a bad o2 sensor or something?

I'm told that you'll need to drive for a week or two to have the computer fully adjust to everything... but that's just what I'm told.
If after a week or two things haven't improved, take it to a mildly performance-oriented shop and have them do a full system analysis.2011 Mustang GT Premium, MT82, Kona/Saddle, HIDs, 3.73s, 19s, hood/side stripes, UPR 1.5" springs with adjustable panhard bar, and UMI solid LCAs and relocation brackets.
