Good on you for seeing the humor,  I'm just not going to get all bowed up over which filter is better than the other.  Not worth my time or effort, I got bigger fish to fry

A lot of good info in the thread with everyone's budget opinion. theleo if you have never owned a diesel then all of this will be a learning curve for you. With all the mods out there the only limit is the amount of cash you want to spend. In my opinion and it's mine only, I would save up a few grand and do your research and piece your mods together. Each one is a puzzle piece. You won't get the added effect unless you put them together. Say for more HP. More air and more fuel equate to more power but if there is no place for the heat to go then bad things happen. Heat and dirt will smoke your engine faster than you can say oh sh$&t! Read up on how diesels work and if your unsure then pick a reputable technicians brain about it. I've done slot of mods on cummins, duramax, powerstroke,cat and detroits and all I can say is you won't get the performance your looking for unless you factor in the variables. Your truck will only be as good as your weakest link which is unfortunately the auto trans. If your not interested in spending a fair amount to beef that thing up then I wouldn't put too much into the motor. Trying to get HP on budget might get your pocket book in the end. Do your reasearch, buy your parts as you can afford them and then do it all at once. Injectors, turbo , intercooler, exhaust, bump your timing. And then of course your trans. Lol. Good luck!

Got my hands on the truck for a couple of days to be able to haul wedding stuff. Being able to have my hands on it and a little research shows me it's a 91.5 (manufacture date of 9-91) with a 518 automatic transmission with O/D. With an empty 4 horse goose neck trailer it wasn't to hard to get it to 75 mph on flat ground (still sucked up diesel in a hurry though) and riding around with the trailer off 75-80 mph is pretty easy.

I appreciate all the advice you guys have given me. Looks like the first steps will be getting the KDP dealt with, adding gauges, and switching out the exhaust when funds and timing allows. It has an intercooler so I'll skip that step and go on to injectors and probably leave it at that.
