So I know that I want the three gauge A-pillar with EGT and boost but I'm not sure if I should go with a fuel pressure gauge or a tranny temp gauge. I do tow a 22 foot boat but not very often and a small trailer every once in a while so I'm not sure if the tranny temp gauge is needed. I still have the original lift pump and I'm at 117,000 miles so maybe a fuel pressure gauge would be helpful to know if its on its way out. Thanks!

 

From what I've seen, the tranny temp is important, but fuel pressure on an 03-04 is pretty important too. I would plan on both, but get the fuel pressure first. I would also get a new fuel pump, whether it be a stock replacement or upgraded (recommended).
