My Suggestions:
  • ARP Head Studs
  • Coolant Filter Kit
  • NEW OEM Engine Oil Cooler
  • Rebuild Turbo

When I say re-build, I mean go through the Turbo and check all your VGT components, chances are you may be loosing some power from a non-fully functioning turbo, make sure to inspect the unison ring for rust pits and make sure to use a scotch brite pad on the surface before re-assembly and also apply anti-seize to the ring and vanes to prevent it from sticking in the future.

You have an '03, the whistle on the '03 is incredibly loud when straight piped.

Whether stuff was replaced/updated or not, you need to read that link, your ECT/EOT delta will tell you if your oil cooler is up to par. Fuel psi is critical to insure healthy injectors, so is FICM volts.

Gauges/monitor will tell you what needs to be done to insure a healthy motor. Along with keeping up on the maintenance.

I agree with a monitoring device like the Edge. You need to see what the condition of your motor is and this way you will be able to see how different mods affect your motor. That is where I would start then go with what performance machine said.

i dont know the lingo yet so what is ect/eot delta, and how do i check it? also how do i check fuel psi. get a gauge installed? and what should it read? also the FICM should i just check it every once in a wile or do they have some kind of system monitor for it. im new to diesel and very happy i made the switch by the way, so bare with me

This is typical for all the 03 trucks, the amount of vanes on the exhaust side is different on the 04-07 trucks. They changed it due to noise complaints by customers. You should be able to visibly tell wether your studded or bolted by looking at the passenger cylinder head. I will take pictures tomorrow morning to show the difference.

ok thanks and i have some pics in my profile of turbo and was looking at some videos on you tube and i think my turbo is stock i do have the edge installed so i can see the EGT,tranny and water temps on the monitor. how ever what should i set the limits at i think they are 230 water 1300 EGT is this good or should i go lower the EGT never goes past 900 yet and the temp runs at about 203 on the high and 194 on the low trans is like 160 on the high 145 on the low are these good temps

No worries man we'll get you up to speed. ECT: Engine Coolant Temperature. EOT: Engine Oil Temperature. You are looking for less than 15F difference in temperatures when the engine is at operating temperature cruising on flat ground at like 55-60mph. Yes fuel pressure can only be checked by installing a gauge or expanding an Edge CTS it should read around 60 psi and be above 50psi at full throttle. FICM is fuel injection control module and that voltage should be 48v plus or minus a volt and should be able to be read on an Edge.

1300 is fine for the EGT alarm. IDK about water but the temps your truck is running at are fine IMO. Hope this helps. So do you have an Edge?? CS or CTSS?? EGT Probe??

I wouldn't necessarily take an engine that is running good, with a good oil cooler and egr cooler (or deleted egr cooler) and rip the heads off just for the sake of studding it unless I had 5 grand sitting in my pocket with nothing to spend it on.
You may never need to stud it, plenty of these trucks out there with stock bolts without an issue. Don't start fixing things that are not broken unless you have very deep pockets.

I put the air dog fuel system on and haven't blown an injector since. It uses a better filter and water separator. It also generates less air than the stock system. At $750 it seemed like a no brainer.

I would reccomend the CCV as well, it will keep all the crankcase ventilation (oil) out of your intake system, BD Power makes an awesome kit. Yes, you may upgrade your current Attitude to a CS or CTS unit. :thumb:

when i got home from work i checked out the ccv on the truck. shure enough the intake tube had oil in it and ware it came in at the bottom of intake tube the connector was broke so some of the ccv oil was leaking out the bottom of intake tube and dripping on the motor. so i took it appart and cleaned it all up, went to the parts store and got some 1'' heater hose and ran it down under the truck all the way back to the fuel tank. and just left it open for now, im going to order a filtering canister today to finish it up. then i cut out a pice of metal and pop rivited it over the hole on the intake tube. (with some RTV sealer on it) all in all not a bad job if i do say so my self.
