I want to chip my 03 common rail, curies about good or bad point of the chips that are out there, kinda leaning towards the edge juice with the monitor, would like to monitor rail presure but you can witht he edge, if there a gauge that a person can hook up to monitor that?

 

I have the Juice w/ Att and have had it on for over 30K miles, I absolutely love the adjustability and all the gauges being in one place is pretty convient, for BIG power this really isn't the ticket but for a mild increase, and easy adjustability this is the way to go. Also picked up 3 mpg, with a 6-speed and 37's I'm right around 19 mpg. And as for the rail press, I've heard some good things about Quadzilla and their rail press gauge retail for around $120.
