See, that's what would tick me off to the point where I'd just spend twice the $$ and get the Power Commander V with autotune and be done with it. No muss, no fuss, just set it and forget it. Check the plugs after 4-6 months and that's about it. I agree that it is price prohibitive, but good doors cost more than the power adder, and rarely do buyers gripe about the $600+ they pay for them.
Its all about priorities. If your main priority is gaining max performance from your ride, the Power Commander is an obvious choice. While I love a bargain, I have yet to see anyone drop in an EJK and have it work well right off the bat without dealing with the tuning complexities that it can and will bring.
