I am the second owner of this truck. I hate to see it go, but with three young kids it’s time for me to make some changes. I bought this after deployment in 2017 because it had literally everything I would ever want to do to a truck and it’s an absolutely amazing build. There is well over $60k...

I’m looking for some advice on how to troubleshoot this issue. I was driving from TN to MI and towards the end of the trip all of a sudden my truck developed a bad surge and erratic rail pressure. After a few minutes the rail pressure stuck at 120MPa / 17.4k psi. It’s the same pressure no matter...

Looking for 10-12 Cummins MAF and IAT sensors. Picked up a wrecked truck as a project and whoever pulled the good parts off before it went to auction to include the entire intake assembly and MAF and IAT sensors with it. Text or call 914-930-9776 Thanks, Bill

I plan on calling Firepunk on Monday if I can't resolve it over the weekend. Truck has been sitting for the last two months and I got it running again on Thursday. I didn't mess with the trans- just fuel and air. The problem started with no up shifting at 75-% or more throttle. The truck would...

I was driving down the road the other day and the AC all of a sudden stopped working and the air got hot. I check power to the compressor, checked the freon levels, and checked to see if the fan is cycling on. The line is cold when the compressor is on but the air still blows hot. Using the VCM...

Exergy 200% over injectors for 07.5-12 6.7L Cummins. Injectors have around 23k total miles on them, but were sent to Exergy around 9k miles ago to get upgraded to 200% over. I have to original flow sheet from 15JUL15 and they were just cleaned and checked out by Exergy again. These will come...

Looking for some dimensional information and recommendations. I went with a S366sxe for a new secondary. What I'm trying to confirm/deny is whether or not the SXE cover with an elbow will meet up with my piping that's setup for a 3rd gen cover? Or, should I just run the already vbanded 3rd gen...

So...I took apart my secondary to rebuild it with a 360 thrust and severe duty bearings, and I added an SXE turbine wheel. I bought both items from SPTurboost (https://www.spturboost.com). I added oil and spun the compressor wheel to circulate prior to startup. After a few miles of test driving...

I was checking the valve lash and all were good except for #6 so I reset all of the valves and worked my way back to #6 intake and exhaust. Intake was fine, but the exhaust is not... When I loosened the adjuster the rocker slipped off of the push rod. I tried taking the bolt out of the rocker...

Learned a lot in just a few passes. This was my best launch of the night, which happened to be the first run. I was feathering the throttle some and also let off before the finish because it was my first time and I got kind of freaked out at how quick the new truck is: I made a few passes on...

Saw this the other day when I pulled the secondary blanket. What do you think?

Anyone tried this? I'm certain the probe in my 2012 is bad because at idle in park or neutral the displayed temperature climbs from 600 to 1000 after a few minutes. Seems simple since it's still a simple two wire connection, but i don't know if all probes transmit the same signal, or if they are...

When I try to shift at higher RPM (3500-4500) under heavy throttle its really hard to get into gear. Within the last few weeks its happened on two occasions where I can't get into fourth at all- it grinds and I have to wait a few seconds before it will go into gear. When shifting during normal...

Unlocked Smarty SSR 03-07 and VIN locked UDC Main Dongle. You would need a VIN dongle to get started self-tuning, or if you plan on someone else tuning for you. I think most tuners include the VIN dongle in their pricing. $500 shipped.

Well, I got my old camshaft out today and was about to have the machine shop press the gear on to my new 178/208 when I saw that I have broken teeth on the cam gear. None of the other gears inside of the timing cover have any signs of damage. Truck ran fine and probably would've continued to do...

I purchased a set of used ARP 425s from a member on here...they turned out to be ARP 2000s and there is significant corrosion on seven of the studs. Needless to say, I'm a little p***** that this wasn't stated in the listing, but then again it's on me for not asking the question on a knowingly...

The truck just started this today. I'm thinking my CP3 is on its way out. Truck has increased idle roughness and vibration, but still idles at 750rpm. When I push in the clutch as I come to a stop the rail pressure drops FAST down to just around 5250psi and then picks back up to around 7400psi...

Just got ahold of a Kicker CX600.5 five channel amp, a new head unit, and some speakers. The truck didn't come with the Infinity 6 speaker setup, but I'm adding the 2 x 3.5" dash speakers. I know can power more than one speaker with each channel, but I am curious to know whether or not I can...
