Hi everyone. Just joined the group.

I have a 2015 Cummins 3500 6.7l. Cab and chassis.

Here is my situation.

My turbo just died.

I have to replace it and I am thinking of why not putting in a modified one from the stock 54cm. To the 67cm and get more boost.

Why not right? I should get more power more mpg etc.

Now secondly I am thinking of plugging in one of those simple performance chips.

It sounds like a good combination RIGHT?

I will have all of the emissions on the rig and be legal.

Now my concern is when I have more boost. From the turbo and the throttle valve closes then what?

Should I just remove the throttle plate or what?

Or am I just over thinking it.
