My biggest complaint with the Atomic and EZ, in anything other than a stock replacement capacity..........is you can't change ANYTHING. You are totally reliant on the tune and calibration the box chooses to run. On the Holley Terminator, it uses the same HP ECU as other kits. Meaning if you WANT to, you can plug the laptop into the ECU and makes changes as you desire
I dont have many miles on my Holley unit but so far
I've been happy with it... if I wanted more power I
put in bigger injectors to support the power.. the box
takes care of it... I dont have the timing hooked up
on it yet but I will come spring time... that way it
will control both the fuel and timing
