I have the stage 3 plus fueling kit on my 2001 and drive a 150 mile round trip commute. I'm rocking 20mpg with a light foot and I keep hearing other setups rocking 23 or so. Yes, gotta pay to play, but are there tuning options to get better cruising efficiency? I'm concerned about getting a tune that won't be aware of the larger MAF and injector sizing.

Thanks
