hey everyone im new to this wonderful forum,anyways ive got a 2002 dodge 2500 single cab diesel and everything on my truck is stock so where is a good starting point as what i should upgrade first. I want to add some power but nothing outrages just mosty for towing.

I would start with EGT, BOOST and FUEL PRESSURE gauges. Then if you have sufficient fuel pressure, go with an edge comp or good set of injectors.

I can't see your signature (if you have one) but if your running an auto you may want to look into a trans temp gauge also. But otherwise I agree with^^^^^^. Make sure you have sufficient fuel pressure for the VP or you will have a costly mistake on your hands.
