So about 2 weeks ago I bought a 91 IC Dodge Cummins 5-speed without a bed. Well the last few weeks I've put a nice flat bed on it and decided I wanted to put some performance upgrades on it. Now I don't want to go to crazy right now but I was thinking for starting out I'm going to put a nice air filter on it. Run 4in exhaust pipe from the Turbo back to a 5 in stack behind the passenger side. Maybe put a fuel pin in the pump? Has anyone done any guages in the cab? I know I should put a pyrometer in so I know my exhaust temps. Does anyone have any suggestions for me? Or have done the things I want to do and have some tips for me? Any ideas and input would be greatly appreciated!

 

First things first GAUGES!!! def pyro and boost
Then do the intake and exhaust stuff like u said
id start out with turning the pump up and see how u like it (if it already isn't) and a fuel pin if u want it
