I just bought a 97 dodge with ~170,000 miles on the clock. It has a plate and is timed. I am putting on gauges (pyro, boost, and trans), BHAF, and 4 inch exhaust. With this many miles, what is something I should maybe spend money on now so that i don't have to when/if it breaks. (exhaust manifold, injectors,etc) I obviously want more power but I would rather put some preventative maintenence into the truck first. (the truck is from Michigan if it matters) Oh and the ATS transmission only has 30,000 on it.
