Alright guys first to start this off, no hazing and honest opinions right now. Have a 09 LMM duramax. Fully deleted with EFI live, 6" lift and 35's, all that good junk. Lately been contemplating selling it and buying a 12 Laramie 6.7. Now have any of you guys did this and been happy with it? I know the duramax in and out. The 6.7, not so much. Mom has a 08 Megacab Dually EGR delete, smarty junior, 4" exhaust, leveled so its not like I'm completely brain dead on the subject. What is a good starting point for mods and what is needed to get to 500-525 to the wheels?

I'm no expert but if I had a professional opinion it would be the following. Obviously the first thing you would do is completely delete the truck. Egr and dpf. That's a given. Next I would address the turbo. Again I'm not an expert but I can't imagine the stock vgt supporting 500+ hp. 2nd gen swaps are popular but it also depends on what you would use those 500 horses for. Towing, racing that kinda stuff. After the "air" mods you would address the "fuel" mods to match your goal. From there (more specifically after you delete) you would seek proper tuning and more or less that's about it. Of course supporting upgrades like studs and transmission would be helpful but that's a quick rundown. I can't do all your research but can point you in a good direction, one of many. Hope this helps. Now convert to cummins!

a tune, and a turbo will be able to get to that number (with really good custom tuning 500 could be had with the stock turbo, but it is stupid hot and smoky) with an s400 on there 550 is easy to achieve.

I ran a mini maxx with mcc and overdrive with my s480 with no other mods without any issues. I put in studs, springs, and pushrods for piece of mind more than because I needed them (the math put me at 550+whp)

Alright well I know with a duramax, EFI live, intake, lift pump, and trans will put you right around there.
But okay here's my list in the back of my head
Intake
MM with MCC custom tuning(not sure who)
Trans
Lift pump
EGR delete
Head studs
Traction bars
5" straight pipe
s467

The swap to fit the 467 will come with an intake (depending who you go through for it (I like source automotives kit) it'll either be 5" or 6" piping) it will also delete the egr cooler, so don't waste your money on a delete kit. trans will live for a while at 500 (I know on guy who's been running 550+ through his for a year and a half without it grenading. It's not really happy, and has thrown a few trans codes, but it's still running) lift pump isn't really needed at 500 unless you're after the extra filtration (anarchy has tested to 8 or 900 horsepower with the stock in tank pump) studs are always a good idea. As are traction bars, and the 467 is a nice little charger that'll make good numbers. I know many people that are happy with tunes from anarchy (the guy to get a hold of is tomeygun on here)
