LS-ONE_DAY

I have a '99 Formula A4 with 2.73's. When it was just Borla catback and lid I was getting 22.5 mpg mixed with a good amount of spirited driving. That was in the Summer last year. Since then I have added the mods in my sig and it's gone down because of the converter, It's probably like 19-20 mixed, but I can't really say for certain because I can't drive it consistently, it's too much fun to try to squeeze out every single .01 mpg like I do in my daily.

I can definitely agree about the colder weather hurting gas mileage though. Plus, in the winter pretty much every start the gauges sweep, reset, and then come up to where they should be and this clears my current trip so it's hard for me to even calculate mpg unless I have a pen and paper in the car to record mileage driven. Only does that when it's cold, no clue why.
