I'll start with my vehicles one 95 3500 CC 2wd auto (no real mods yet), second 98 Durango (westin safari bar, catback duals), third 94 Acura Integra (I know but you have to have something to sacrifice to the door ding gods at Wal-Mart) I have alot to learn so bare with me, I'm a pretty good shade-tree mechanic but all the diesel stuff is new to me. I going to start my mods with a gutted cat and fat duals (no muffler) and am already looking at the details for a MoparGuy air filter, I would like some input on other mods but not so much as to jeopardize my transmission. My wife and I are big NASCAR fans and go to 4 or 5 races a year, as matter a fact we just got back from Bristol the other day, where I had a break down on the way back (fan blade came off put a hole in radiator but thats another story). I have a 98 Jayco 30' Eagle that we pull to the races and a bed full of stuff generators and such, and thats why I'm looking for more power. The truck has 160K, I have only had it for 4 months and have replaced the wastegate actuator, lift pump, K&N filter, NAPA fuel filter, had the overhead ran, I still feel that I'm lacking power. Also I realize now that I need boost and egt guages, where can I get some at a reasonable price? Sorry this is so long but I have alot more ?'s to come, thanks ahead... ... ... ... ... .
