Silly question time...

In Short Yes.
the best way you could tell and gauge the difference would be to use a good GPS unit and measure your actual speed per rpm before and then again after for an example the Std Rocket comes out with a odometer that reads true but the speedo reads 7% higher so if you put a higher profile the such as a 240/55/16 (std fitment 240/50/16) it brings the variance back to only 2% higher but also means the odometer will read 5% lower so when working out fuel economy you need to multiply the odometer reading by 0.05 to get the correct distance covered, not hard once you get used to it

No if you adjust -7 in TuneECU the speedo will read true but the Odometer will be down 7% so you would multiply by 0.07 to get correct odometer reading

Sorry but ...... well you know....... I just had to tell you incase you came back and said your fuel economy had gone south .. .. but with that info you will be able to work it it out right

Mate,
Using your example above - if the odo is down 7% would not one multiply by 1.07% to obtain the correct mileage???
