Not sure what's going on here but We did a 2nd gen swap and a set of nozzles for a customer and shortly after he got it back it started turning off and back on while driving it, literally everything turns off, gauges all reset and sometimes the clock on the dash resets... it happens really fast...

I have a brand new fluidampr balancer here for a common rail and was wondering if it will fit a vp44 engine?

We're in the process of building a drag truck and looking for some opinions on who makes the best tuner for the vp44 trucks. It won't be driven on the road anymore. At the moment it still has a standard output pump on it which will likely change in the future. Looking for something that will...

Installed my new vp44 tonight and can't get the truck to run unless you use starting fluid. I am 100% sure the keyway is in its slot perfect. I've replaced several of these pumps. It has a fass on it which is working perfect. It just doesn't seem to have any pressure at the injector lines while...

Hey everybody, we're in the process of building a pulling truck but we aren't quite sure what class we would be pulling in. We wanted to build a triple turbo setup but is that legal in any classes? We would only be pulling at local fairs and nearby pulling events. I'm just not sure if it's going...

I've got a 99 and can't get the thing to run. Bought it for 500 bucks because the guy had no knowledge for diesels. It had ran when he parked it and it sat for a few years then wouldn't run. I figured for sure it was the injection pump because it threw several codes for it. I tried to get it to...

Hi everyone, this is going to be my first time pulling and I'm not sure what gear I should be using? It's a built 48re and I have everything in my signature and I don't have proof yet but the truck should be making somewhere around 1000hp. I saw a lot of guys said to use 2nd gear 4hi but I feel...

Hi guys, we got my buddies truck back together with his 100% over injectors. He has to run his stock turbo for a while until he gets his new setup. With his stock injectors the truck was making 44psi pretty easily and now with the bigger injectors its only making 37 psi but is significantly...

Finally got around to getting my compound setup on! 66 over 80, I didnt really wanna run the 66 with the 80 because I was afraid it would end up being too big. But i already had it so thats what I had to use and man does it run good!! Now im wondering what kind of power you guys think ill be...

Today I noticed my truck was running fairly rough, Almost like a miss at idle which seemed to go away as rpms went up. Well on my way home my throttle pedal just stopped working and check engine light came on. Threw two codes for APPS sensor (dont remember which ones exactly). One of them I...

Hi everyone, I am in the process of getting everything rounded up for compounds and have a few questions. I have the large turbo which is an s480 and just need to order the Stainless Diesel s300-s400 compound piping kit but am afraid the 3.5 inch cold pipe will not work with my turbo. The s480...

I noticed today when I was cruising up a mountain my rail pressure kept dropping off? It usually runs around 18k and at the start of the mountains it's good but after about 10 seconds you can watch it drop down to about 13k?? As soon as you get on it, it comes right up to where it should but...

I am in need of someone who is still doing udc tuning, I have been trying to get ahold of some places but haven't found anyone yet still making custom tunes for smarty since HP tuners came out now?? Does anyone know of anyone still selling custom tunes?

I finally got around to installing my new cam (hamilton 188/220) exhaust manifold, and intercooler! What a treat it was to get the new tappets installed.. I am very pleased with how the cam seems to spool! I noticed that my cruising egts actually have raised 100 degrees when climbing a...

Hi guys, Im looking to build another engine to swap into my truck to save the down time. It is an early 04 and seems to be fairly hard to come across an 03-04 engine at a decent price. My question is, are the blocks and heads all the same up to 07? I know they have different injector spray...

Hi guys, I believe I have all my information listed in my signature about my truck but Ill go ahead and list the main stuff. Im wondering what sort of Horsepower you guys think ill be making? I currently have an AFE intake, 100hp injectors, 66mm turbo, Fass 150, PPE dual cp3s, and smarty UDC. I...
