New Gas mileage after Mods

[svt03cobra10th]

Well, ran my first tank of gas after the power mods. I got 16.2 mpg (that is in town and using every bit of the 14.5 lbs of boost or so). I never ever got that before. The best I got before was about 15.6. Can't wait to see what I get on the highway.

My mileage went up 1-2 mpg after mods and has been improving slightly ever since. At 3700 mi now and last tank was 19.3; 50/50 city highway.

I've had the opposite effect, went from ~19 down to around 16.

Might the increased mileage be related to a leaner tune?

I was getting 23mpg highway with a K&N FIPK, 2.9" RR upper and Borla Stinger Catback. Haven't done a mileage check since the latest changes.
