Good evening all,
With gas prices going through the roof, I am looking to maximize my gas mileage. I do most of my driving on the highway and want to start with an MSD 6A unit and then follow that with a Diablo-Sport tuner for 87 Octane. Can I mix the two and how will that affect my performance? Will the tuner wipe any benefits from the ignition?

Thanks,

You should be fine to run the 87 tune with the MSD.
