They are all about the same. If you have the power puck already, keep it. If not look for a used one, or Edge EZ. I would not buy one new.Without going smarty what box would yall recommend with out tapping pump wire for best bang for buck?
$500 code reader that doesn't work on anything else?I ran a puck smarty stack, wasn't a bad combo, use puck the puck for timing and smarty for fuel and its a lot cleaner. Added bonus you get a code reader too
