So before we did any modifications, my family and I took this truck on a road trip for about 6 hours each way - bone stock. Our trip was from northern Ca. down hwy 5 to southern Ca. We loved the truck, but soon into the trip I had a ton of idea’s to help with the ride and handling of the truck. I started the modifications off with the list above. After the truck was done, we took it on another road trip without the faith wheel toy hauler. Both myself and my wife saw a big difference. The over-all ride was completely smoother, not so bone jarring when it went over bumps in the road. Around town it’s great. On our freeways we have those break points where the concrete meets and you get that very uncomfortable “thump thump thump” feel. Well, that’s also improved dramatically. The Toyo mud terrain tires are a bit louder than if I would have picked all terrains, but I need the muds for the grip when I pull my toy hauler into the sand when we camp so I don’t mind the noise.
Next on the install list:
Amp electric steps
Auto Meter Nexus gauges
PPE EGR delete
DPF removal
Fuel tank
Lift pump
Nicktane fuel filter
H.I.D. head & fog lights
On board compressor
Air horns
If you have any questions feel free to post a reply or PM me and I will be happy to help.
how did that RBP exhaust fit? i really want one but i have never installed anything from them on anything and im always worried about fit becasue i hate pissing with "bolt-on" stuff!
but the way the pic of the truck on the beach with the weekend worrior in tow really makes me wanna move back to cali! sweet combo man!:thumbsup
Buck-
The RBP kit was great. Not bad at all. I have since taken the RBP off and installed a MBRP 5" w/DPF removed. If you want a RBP kit let me know.
I see you just stepped to a Duramax from a 6.0L. I had a 06 F250 6.0L also I just sold,
I loved that truck but these new LMM's really kick ass. With removing my DPF and running a PPE tuner I pulled my 40foot 5er loaded and still was keeping 14mpg not being light on the throttle:gearjamin
Yes it was. The Dunes are not as bad ass as what you have in SoCal but they are great for a short weekend trip. I hit Glamis when I have a week to spare.
Yea we go to glamis a lot. Been to pismo a couple of times. It seems everytime we go there is always someone stuck. All these guys get pissed when a 17 year old pulls them out with a bone stock chevy. It has happened more than once. You will definatly not be getting stuck with ur set up though.:rof
Yes I remember those days. When I was 17-19 out there you would pull a ton of people out and they would hook you up with a few bucks and a thank you. Now if you help someone they will sight you because the tow company's have the beach front rapped up for business.
Nice Dually!!! I am not a real big fan of the stock bed but yours looks Kick A$$!! How are you Knockin down 14 pulling a load. I cant get the work rig to clear 10 loaded and 12 empty.
I pulled the DPF and I am running the New closed AFE stg2 with a PPE tuner. I just received a EFI and I am working with a tuner to see if we can get more MPG. I will post what happens.

***** Up Date 7-1-08 ***** Nor-Cal Nick’s 2008 Chevy 3500HD LMM *** Up-Date ***
Since the last upgrades to my truck were done a few months back, the first new change we made was removing the DPF system. This first modification was done as we searched to satisfy the need for more performance, HP, and mileage. With the removal of the DPF, the install of the MBRP 5” turbo back system, and updating my PPE performance tuner to turn off the DPF feature, we obtained these stats.
PPE lev. 1 / no DPF- While towing a WW3905 (39 foot) 18K fifth-wheel trailer under normal towing conditions, pulling hills I was looking at 14mpg average, round-trip. This was calculated over the course of 3 different trips. All was calculated by hand (mile drove vs. gal.’s used). I also had a chance to run my truck on a dyno (DynoJet) with a PPE level 6 loaded and no DPF. At this setting I was able to pull these dyno runs:
4-5-08 426hp./688tq.
I was very pleased with the mileage I was seeing with the PPE. I started looking at EFI Live, not so much for more mileage, but to take my tuning ability to the next level. I ended up talking to Nick with Duramaxtuner.com. There are a ton of tuners out there that are getting big HP #’s, but that’s not what I’m after. I wanted someone that would take the time necessary and work towards obtaining a good power tune for towing a large load, and at the same time keep mileage in mind. As of right now, we have been bouncing off each other to get where I want to be. I will have more info later as we go on with testing. Nick has a library that you can pull tunes off of, so I installed a few of his tunes for some great street power. I had the chance to run his “400hp Fun Tune” on the dyno with the same mod’s as I had ran the PPE before. Here is what I ended up running:
6-7-08 “400hp Fun Tune” 414hp./786tq. Also, 6-7-08 “LMM08_08_HOT_6.07.08_Highboost” 440hp./805tq.
So with some tuning, I picked up a few HP on the dyno. I would also like to add that “out of the box” the PPE unit is great for power and mileage as you can see from the outcome.
Next we needed to upgrade the fuel and tranny. I started the fuel upgrade with a Nicktane Filter kit to keep my fuel as clean as possible. To get a steady PSI up out of the fuel tank, I called Steve @ TTS power systems. He has a great flow-through fuel lift pump kit that fits right above the fuel cooler - very discrete and quiet. He also stated that it would be a good idea to open up the fuel pick up in the tank as well. We also installed a TransGo Jr. that will help agaist clutch slippage with my power upgrades.
One product that I had seen talked about recently was called the PCV reroute. I saw a few people making up there own kits with parts that they had obtained from a local automotive store. I also saw a post that Tony Burkhard had made a VERY nice little turn key kit. It had billet fittings that bolted to the valve covers, so I had to have it. I called Tony and ordered a kit. We didn’t get a chance to talk for too long, since both of our phone lines were ringing … but just a couple days later I had a box sitting on my desk that had all the parts needed, including those kick ass billet fittings. Thanks Tony!!
I want to give a big “THANKS” to Titan fuel tanks. They have been telling us about the new Super Series larger tank that was soon to be released. The only problem was that I was running out of time and couldn’t wait for the new series to come out to fit into my schedule. I had a bunch of parts ready to be installed into my truck and needed to get a larger tank on at the same time. I was on the verge of telling them to just go ahead and ship me the most recent Gen V. tank, when they called and said they where shipping the first tank of the new series to us.
Thank you Titan Fuel Tanks, this new “Super Series” 62-gallon tank is HUGE!!!
