I'm frustrated with MPG! I was getting near 16 with the A9L ECM (5.0/GT40P heads/Explorer Intake/3.73 gears/31" tires/M5ODR2 trans/EDIS ignition/no A/C) Only change was to install MegaSquirt MSPNP2 ECM. My tune looks good on all the plots and it runs great except for some stumbling at less than WOT at 2800-3200RPM. Now I'm getting 13MPG. I may have hit a wall in the HP vs. economy but I'd sure like to get a couple more MPG.
