Have a 2017 GMC 3500 C&C dual fuel tanks throwing a random P0087 (low rail), reduced power, sputters, then shuts off. Wait about a minute, start truck, and runs fine. Will not happen while driving, only when you start the truck. If you start the truck and it runs, it will not give you any...
Can a 2016 LML transmission be made to work in a 2018 L5P? Have a fresh built 2016 LML transmission, customer backed out. Understand the input shaft and converter are different. Anything else need changing or not possible? Thanks.
Going to be moving to Phoenix here in the next few months. Trying to get an idea of where to go. Have an 11 year old so schools and safety are on the top of the list. Wife will be working at the VA hospital, want to keep her drive at 45mins max.
I will also be moving an entire shop and the...

Truck is a 2012 LML with an H&S tuner, head studs, and a full delete kit. Has a new surge tank and cap. Water pump and thermostats changed when studs were done.
The truck will get up to operating temp and some of the coolant will flow into the fender side of the surge tank. After the...
Down pipe back exhaust no longer available? I've noticed very recently many "big" diesel part sites no longer carry full exhaust systems. Basically 07.5 and newer are filter back only. I also checked Ram and Ford, same deal. I guess its back to ebay for diesel parts???
06 LBZ has an odd braking issue. When the brakes are applied truck stops fine until just before you come to a stop. The steering wheel will see-saw back and forth like the front brakes are alternating back and forth.
System has been bled 3 times, truck has braided steel lines. Automated...
I've been messing around with my 17 Colorado. How much line psi can these handle without causing problems on a stock transmission? The line psi table by RPM/Gear in EFI live shows 105. The max line PSI table shows 275 with a max clutch psi of 218 and a max PCA of 110.
I was able to...
Any input on pressure boxes for the 2016 Allison? I see BD and ATS make one and wanted to see if they are any better then the G-solenoid mod.
I've already done the solenoid mod and now have a transmission tore down with smoked C1 clutches. After building it I was thinking of adding a...
I am looking for a link to a cheap fiberglass hood. The hood is going to be cut for a hood stack and waste gate, it will also get pinned.
The only thing I can find when searching are the expensive cowl induction type hoods. Thanks for your time.

I was able to find a guy with a dyno close buy willing to test my truck, the only problem is that he is a gas only guy. He didn't think the dyno needed a load.
What load do I need to have him start with to get a good reading, fairly big turbos GT45R/GTX47? Dyno has a dual current eddie...
Has anyone deleted their power brakes and gone to a complete manual system for a drag truck? I would like to eliminate the the hydro-boost and all the ABS stuff. I have seen a few pullers do it but I don't think stopping power is as much of a concern. Again this is for a drag only truck, no...
I have a few questions for transmissions options in a possible super street truck
1. With advances in tech on the Allison will it hold 9.XX passes for a race season, or will tear downs be needed every few races?
2. If the Allison can be made reliable on 9.XX passes what kind of costs are...
