I think i got the Hybrid 370Z

Is this normal....averaging 40mpg highway after tuning/supercharging?

I did about 70mph for 600 miles and that's what my gauge said...I'll have to check my fuel fill ups to confirm. Just thought this was weird. Before the supercharger install, best I could get was low 20 mpg

Larger fuel injectors => ECU calculates via pulses assuming stock injector size => higher MPG reading.

So that explains it. Thanks for the info, bro!

Do not trust your miles remaining screen. It's off just as much as the mpg.

I honestly haven't heard of any updates from UpRev whether they've opened up the tables for calculating MPG. It would be nice to change the injector value so it can be useful again. I hand calculate MPG with my setup, and it's 22 MPG peak combined for daily driving.
