Stevo F Posted June 21, 2014 Share Posted June 21, 2014 My MPG's still seem to fluctuate. I wonder if the ECU retunes the fuel mixture when you do a mod like MSD coil or intake. When I first installed the intake pipe MPG's went from 24/25 to 27 MPG, but now it seems to have settled back to 25/26. It's also hard to compare between tanks as my wife has been driving the car more (on shorter trips) in the past week or two since we got rid of our Corolla.
