The build i'm at is almost stock besides a Neuspeed power mod at 93 octane, CTS intake, and a muffler delete. whenever im accelerating ill get about 9 mpg in 1st and 2nd gear, then 15 in 3rd, and it will get to 26 ish just cruising at 2000 rpm in 4th, not 100% sure about the mpg cruising at 4th that's just what i remember whenever I've looked at it.

honestly this could just be a normal car doing normal car things, the car doesn't seem to be running rich or lean, so please let me know if i'm just being a paranoid dummy.

let me know if that doesn't sound right and ask any questions or tests you'd like me to do if that would help.

Turbo charged engines can suck fuel like no other when accelerating. The 1.8t isn't considered thrifty in city driving especially while accelerating.

drive around and calculate the MPG over a full tank of fuel, I wouldn't be shocked if i just did city driving i got low 20's high teens in our stockish 1.8t with 4Mo.
