What is the normal max boost on a 550 HP, C-15, 6NZ engine?

Howdy Loaderlue,

Thanks for your reply it’s nice knowing my truck is performing as it should. I don’t need any more power but being a normal guy like most I would not turn down more if it didn’t cost a lot or hurt reliability.

Many years ago I drove to put bread on the table now I drive for fun BIG difference, hope there comes a time when you folks can do the same.

I have an '01 Pete 379 with a 6NZ 475, no custom flash files. Turbo and exhaust manifold were upgraded to a BullyDog set up. Dyno says around 535 WHP. Max boost when I'm pulling a hill is 40 psi at 700 to 800 degrees.

 

Howdy 6NZoom,

Sounds like you have a runner.
