EFIE VS MAP, which is more neccessary
I have an 01 dodge 1500, I have both a map enhancer and efie, the map enhancer did something to my map sensor and I needed a new one so I just stuck with the efie only. Both can lean out the fuel. I noticed some vehicles have the map sensor on either air intake or intake manifold. Does this make a difference, all vehicles I do installs on I only use an efie now except diesels. What is wrong here?

It's generally accepted that the o2 sensor is the king of sensors and has the final word on your vehicle's mixture. Given a choice of one or the other, I'll always go with the efie first.
