i have a 02 dmax with edge juice with attitude, cold air intake and a 4-inch exhaust. a recently tuned my truck with efi live. iwas wondering if i could leave the edge unit still plugged in on zero for the use of the gauges. i switch to efi live because i have gone through 3 edge units in 6 months. but i really like the features of the attitude for guages and soforth. i m not interested in stacking them together for more power. the efi power is a lot smoother.
