    My money is on both. I plan on installing both on my GMC Serria 5.3l pickup.

    ok. can you explain what the difference is? I thought they both serve the same purpose, to make the car run leaner right? so the EFIE uses the o2 sensor voltage to adjust the reading, but how does the map enhanzer work? or is it a maf enhancer?
