Yep., as long as you have positive pressure I would say it is ok to drive if you need to. I wouldn't make a habit of it, but life happens and we can't just pause everything because of something like this. there are a TON of stock 24v trucks drivng around wiht no FP gauge and no fuel pressure at all haha.

Not sure why it would matter one way or another.

Humm odd. Only seems to be an issue when timing is up near 20*? I've never had this happen on my long highway trips I will keep an eye out for it.

So one thing we know for 100%. since TPS is at 0 the quad is not sending a signal to the vp44. Does the miss come back when ac kicks off? Or does any load seem to kick it out of its funk?

So give me EXACT details on when this "lope" happens. As many sensor input values as possible That will help me figure out what is the cause of it.

You told me not to drive it hard until I retorque? Gotta get new intake gaskets tomorrow then I am off to the races... and yes I am bumping my rev limiter to 3700

hopefully the bugs are ironed out haha, I dont want to change anything else. Now we are just figuring out who things work with the ECM and our trucks.

Bigger your injectors are the more you need the control of the Quad.

if it aint broke dont fix it.

@TFaoro was here helping me get studs and springs and push rods in.

Fueling lower than stock is VERY helpful with bigger than stock injectors. HP wouldn't be lower as your injectors make up for it. By fueling we mean the actual fueling message to the VP44, think or the fueling message / commmand as a 0-100% for 0-235 hp on stock injectors. %50 = 117.5 hp etc Now you add bigger than stock injectors, the ecm doesn't know that the injectors flow more than stock so it is still commanding fueling like it would with stock size injectors. So rather than %50 = 117, %50 = 200 hp. Now move down to your offidle fueling, there becomes a point where even the lowest amount of throttle movement / change is too much and you get smoke. Our trucks in stock form really use about %25 - %85 of fueling, Using the quad to pull that %25 down to %15 or lower can give you a lot more fueling resolution. Again still the same power down low, but you are able to "recalibrate" the ecm tuning to match the larger flow rates of the bigger injectors.

Or at least gooder.

but the difference is big

sounds like they are bad to me. I'd be looking for a replacement.

Are you running a cruise timing of 2 now?

great info. What RPM was it missing at? overall 20* isn't that much depending on the rpm.

yea you would never get a 72 or 75 to spool as a single on a vp truck without some SERIOUS fuel.

You would hate life with a big single trying to tow. start with the small turbo and add a bigger one if you want it later.

lvl 1 is oem timing, whats happening is the screen is getting the wrong value ot show you. No real issue, just a minor bug.

on lvl 0? it jumps?

I'd do the t3 housing personally. As for injectors I would talk with @dieselautopower about it. They can get you set.

I would like to see over 12.4v+ after sitting with a full charge but @Mopar1973Man would know better. I would have your batteries load tested if you are concerned

I'd do a 62 sxe and some 7 x .010's

6 cyl mode just sounds like a normal cummins running at 1200-1300 rpm.

You will like it, if you really wanna speed up the warmup process get a EB installed. A few minutes on 3 cyl mode with the eb on creates some serious heat
