im getting a 99 psd automatic and plan to buy silverline 4 inch exhaust, dp tuner, ITP overboost anhihlator aem intake, and bully dog shift enhancer and gauges. im wondering if im going to need to upgrade my fuel system so i dont starve my fuel pump? im not going to have to much money left over so im hoping i wont need it right away.
no you should not need to upgrade fuel system. but why are you buying the bully dog shift enhancer, the dp tuner comes with a trans tune on it. and its a pretty sweet tune too. you might want to do the fuel shim mod though.
the dp tuner comes with transmission tunes? i didnt know that. will it hurt to get the bully dog shift kit along iwth it? also what is the fuel shim mod and how can i do that? thanks
