I would do the gears first. Then the whole tuning aspect will change so don't do any injectors or turbos till you get the gearing done. I'm betting the turbo(s) you got now are too big.

I think I'm getting it.

Again the confusion sets in. But you look at your graph... In all cases, it's 2.5* timing pull. But above you stating 1.5, 2.5 and 3.5* of timing pull? Maybe why I never play with this setting because I still don't understand the math behind it and how it functions.

I think he's thinking 3rd Gen track bar. Typically the ball stud fails on 2nd Gen track bars.

Most likely won't need the turbos after re-gearing the axles. Perfect RPM range for towing on 37" inch tires at 65 MPH.

Absolutely its called rolling resistance. Final gear ratio of 3.00 is way to high of rolling resistance and put a huge amount of load on the driveline and drivetrain and the engine so the net result is high EGT's as the truck is pull ing in a super high gear it was never design for.

Change the gears to 4.10 if you not towing. 4.88 if you plan on towing. The whole EGT problem will go away. Looking cool on 37" inch tires comes with a huge price tag. It will be about $4,000 to re gear the axles. I've just finished this project with a local gent with 37" tires. Now the EGT's are good and low and the power is super.

37-inch tires on 3.55 gears is a final ratio of 3.00:1 which is WAY TOO TALL geared! This will create a HUGE amount of EGT's. For towing performance, you would want 4.88 gears for 37" tire for towing.

That what I was going to ask you why have I found 3 people with the seal hanging on the shaft and blown out of the pump with 30 PSI? Then diesel fuel just dumping in the gear case?

First off you running 37" tires. What is your gear ratio? Hopefully 4.10 or higher.

Might be differences in ECM programming from 1999 to 2002 like on my truck if I disconnect the grid heater line it does trip the CEL.

1989 to 2002 Dodge Cummins engines will do over 1 MILLION miles without a thought. Its the Common Rail 2003 and up that have a hard time getting past 100k to 300k without eating a piston from failed injectors.

So have I on my 1996 Dodge Ram 1500 I've got to replace the rear drum on the next brake service.

This is one of the reasons I tell people to just write down the number and come back the OBDII database here and look up the codes. OBDII 100-999 should be generic but some of the Cummins stuff doesn't fit exactly right. OBDII 1000 and up is supposed to make and model specific and most of the hand held OBDII readers report weird stuff on these 1000 and higher numbers.

Exactly. As long as the APPS is at idle position then the ECM is direct control of idle speed. APPS sensor is not the cause. We do need the error codes use OBDII code reader most 2001 will only report PCM codes and then stop on the key trick.

The only thing over there is the blower for the HVAC system. I would drop the blower and inspect the blower. Lot of times objects and debris fall in and roll around into the blower.

Sure is. Man, I love it when I just pull my cellphone out of my pocket and set my timing. On a VE pump you have to buy the special dial gauge that screws into the center of the pump. This measures the plunger lift and timing. Not a cheap tool. Way easier to just grab my cellphone and Quadzilla iQuad app and set the timing to what I want. If you take look over at 3rd Gen at the Smarty UDC tunning you see what Smarty touch can do for the VP44 trucks.

ECM is fried first off. I would test for AC noise from the alternator. Then clear this code and see if it comes back. If it does the other codes are most likely from the AC noise of the alternator killed the ECM.

You might try to track down @Cowboy he's a 12 valve guru of sort and last I remember he did a port job on his 12 valve head. So he would know about the head gasket job.

Ok. Then please explain how the front seal pops out of a VP44? I've seen 3 reported after having high fuel pressure.

Are you running the current flash on the Quadzilla? Is your iQuad app up to date?

Take the risk of blowing the front seal out of the VP44. Excessive pressure above 12 PSI during starting could create hard starting.

P0191 error code has to do with Rail Pressure sensor. I would verify all the wiring and connections. Then you might consider replacing the rail pressure sensor. You could test the rail pressure sensor by hooking up a live data tool and checking the rail pressure signal.

I gathered you replaced the gear? Which gear was it? Sound like someone didn't torque the bolts properly.

Yeah I know sick they price hike they put on those little valves WH6820 they use to be $8 bucks and cheap...
