Ok I hate the search engine so I'll ask a probable beaten question. I just sold my 99 ctd with my gauges and mods but my new 06 dont know much about it as far as doing mods to it. What do the 06 owners recommend doing. Obviously my 4 main gauges need to come back (pyro, transmission temp, boost, fuel pressure). Any others? Now that I'm done with the prone to die vp44 what do I need to concerned with? I already rebuilt my 99's transmission for the mods how is the new 48re. What upgrades work well with with the common rail engines like injectors and such? Sorry for going over something that probably has been beaten to death but I need to order stuff now so I can get all my mods done before the first payment needs to be made (and the wife steals my checkbook back). And with that let mods list fly!
