So since Cummins increased power output by increasing boost, does than mean the engine will fall apart just like people say it will if you increase power by doing the same with a tune?

I think you know they did a lot more than that!

Virtually EVERY head gasket issue on a 6.7 Cummins is related to an aftermarket power enhancing device.

Maybe I missed it but where was Boost increase mentioned?

No it was not, it was due the drive pressure of the VGT. Notice every HD truck diesel had head gasket issues the first few years they introduced a VGT. Both the LLY and PSD 6.0L also had head gasket issues until they OE revised the stock tuning to reduce drive pressure and carbon build up failure.

I read the boost increase from another article. Also, you forget that I have a Cummins login and can view detailed parts diagrams and specifications of every Cummins engine. I am not saying that this one one did not come with parts changes since I have not been able to compare then yet, but previous power increases from 2007.5 all the way up to 2018 all had zero changes to their CPL parts yet they had multiple power increases via engine tuning which is the exact same way after market tuners are able to increase power. The only difference is that Cummins has to abide by emissions while most aftermarket tuners opt not to.
