Re: Bully Dog performance gear
Go with something like InMotion for a custom tune. As for a gauge I don't know if there's anything on the market that can pull up proper data for anything you would actually want to monitor for the CRD. Most guys used to run the DashHawk but I'm pretty sure it's discontinued.
You could always try the ScanGauge II, I had asked them if they supported the CRD at one point and they sent me a bunch of X-Gauge codes to try but I never did buy the gauge.
The power puck and other products like that just plug into the fuel rail and boost fuel pressure. They're also usually a 10 cent varistor in a box. Huge waste of money and you're much better off putting it towards a proper tune.
