Ok for give my newbness. On my gas truck i run a Dual Aeroforce interceptor guages and a autometer C2 A/F guage. Do the interceptors work with the diesels and the OBD2? I like the ability to monitor whats going on with the scan guage. Also if i get a EFI tune i will want to own the V2 interface and software. What kinda $$$$ am i looking at for the tune and interface. I allready have HPtuners so its hard to justify owning both tunning software programs... I really like the socal diesel over head guage pod. Many of my buddies use that in their trucks. Again my goals are not to have a 1/4 mile monster just a work truck with a decent tune thats not going to eat my tranny and motor.
