68067109AA, may have gone to 68067109AB now.

I double pinned mine, arp bolts and loctite. But ppump 24v that turns some rpm once in a while.

Boost does not blow head gaskets nor does it have any correlation to the failure.....

You cannot change the vin in the pcm with a reflash using a drb III or emulator. A flash update is based off the vin the tool recognizes. What you are asking for does not exist as the controller is locked.

Uh no. It cannot.

PCM CANNOT be reflashed.

No, unless you buy the pin kit with it.

I know. My point is most stop before they are actually limited. Myself included in that.

I know of a mid 700hp truck with nothing special. Just a secondary most will not run as a single.

More has been done with both pumps but requires injectors and turbos very very few would put up with. As well as a better cylinder head (ported).

No idea. After talking to Seth last week it seems to depend on end use. Like the ppump 24v stuff they pump up the pop to clean up nozzle haze. I do not have a line into DDP to ask them.

I do three on a fresh gasket after the first torque and start up.

Smaller injectors with higher pop. Time to find a stock set.

None at all pending you have a tuning platform to tune it. Like the quad.

Correct. It will also produce less heat and smoke. Reduces duration required to get your desired hp.

Isn't that the truth. LOL Nick you are kind of hitting on it but still skirting it. You are missing the roi of the nozzle increase. Takes less time to inject the same amount of fuel. Ecm will over or under shoot as it does not really know you increased the nozzle size. If you still have a stock set of injectors increase the pop.

To add to this. Injector size matters when looking for power. Larger size means faster rate of injection. For 500hp nothing more than a 7x.010 is needed. The caveat there is you are at the top end of the duration scale to get it. A larger injector can support it more easily. Sac vs. vco. Cost. That is it until you get into the larger nozzle sizes. They trade back and forth but vco starts to out perform sac.

I can tell you right now Weston will not sell to them. Don likes 7x.010 nozzles. If you let it run for a few min it should take care of the stalling without having to pull the injectors.

Studs, one at a time completely remove the nut and washer. Relube the stud fine threads, both sides of the washer and the nut. Pull right to arps spec. Make sure the stud is not bottomed out in the block. Where did the turbo come from? Very odd it came with the smaller discharge. The elbow being shorter I get but not the smaller diameter. Is not a drop in at that point.

I wouldn't so much say risk as much as the publicity that goes with it when someone that does not understand what they are getting into asks for something special like this. You and the people in this thread have an expectation of what is going to happen. Joe blow that wants the super duper special nozzles and higher pop because bookface said it was cool won't. Is just a headache for them at that point. I see both sides of this, I really do. Fwiw I tried to get Weston to open up to it. Is not interested lol.

Most fall of or give up. There are some 7 holes that run very very well in a vp application. Most give up as they do not want a laggy all around driver due to turbos needed.

The od still looks like it is close to 3" is it not?

I disagree. lol

It was given up on due to issues with lack of tuning. Y'all need to keep that in mind. There are 2 people that were extremely big into the mechanical injection side. One of them still is. Everything we are being told is old. Yes it has been tried with no success as they had nothing capable at the time to make these work. Weston picks and chooses what he works on.....like Cody found out. This idea is in a very very narrow part of the market. That is ever shrinking due to newer trucks becoming less expensive to buy. None of the ideas or push back are the end all be all. We all have different opinions and expectations.

Mine never have. On either truck. Horn only honks on the 24v.
