I'm researching adding an Edge Juice w/attitude CTS to my truck. I continue to see drivability and reliability issues mentioned without really being defined.

What do these mean?

My truck is an '04 bone stock with the exception of the KD mega-filter and lift pump.
140k miles on the 1st set of injectors (which need changed soon. At the same time, I'll move the CAI sensor, add a 4" exhaust, and open the intake box)

I'm almost certain I'd be happier with a KD custom ecm, But I Rrreeaalllllyyyyy like the CTS gauge display.

If I were made of money, I'd get the KD ecm AND the edge monitor. Maybe I''l just hafta save my pennies and do just that.
