How does car calculate mpg
If you change injectors and go turbo will the car mpg calculation be correct
With Rebel Turbo stage 2 w/intercooler shows 40 plus mpg at 60 and 37 at 80 but overall getting about 285 miles for every 11 gallons
Trying to keep my foot out for a whole tank but pretty hard to do.
So far mileage range shows 330 plus trip meter total 360 total miles.

okay, i have a 2.2 and i got some 18" rims w/ 235/40's, my mpg went down from like 27 in town to around 23. my cousin said that i could take it in to a dealership and they can reprogram the computer for the size tires i have, is this correct?

Recalculating for tire size
My dealer said they couldn't When I had the car tuned by trifecta he made the tire correction. Checked with another persons trip meter to check
over 150 I was 1.2 miles off from a stock car and tires.

Those massive rims and higher rolling resistance will also negatively affect your mileage. It may not be all in the computer.
