Peak Boost?
Was wondering how to tell if your new engine is running full power after break in. The most boost I see is about 35psi on the truck gauge on an 450. Is this normal for others out there?

The 450 and 550 only have 300 HP /600 TQ I GUESS cause of the LOW GEARS. If i had to guess thats why the boost is lower.

Hello all;
A consideration in this discussion is the accuracy of the guage if you are using a factory guage. I hate to say it but new vehicles do not come with the highest quality guages. That is part of the reason why many new vehicles do not have actual, usable numbers on the guages. It kind of goes allong with the idiot lights replacing guages. They fall under the idea that if it is not pegged in one direction or the other it must be fine.
Sorry, not having real, numbered, accurate guages is a pet peve of mine on new vehicles.
