whats peoples average mpg on 3.4 setup?

[x98GTPx]

well, kinda sad but i get about 160 miles a tank (usually fill up 11-12 gal each time too) and average 16.1 mpg in this winter. Funny cause in summer I maintain a 22 mpg but it may be because I rockered and ported my car this winter, something still might be wrong though...

I cannot imagine how rich your car was running if you got 14mpg on the highway.

if he had a cat converter, it was hating his ass.


another note.. some of u guys have real ****ty gas mileage and u should look into that. :th_nervous:
