So my VGT turbo is showing signs of going out.

Exhaust brake is sticking.

My questions are as followed.

Does it require tuning?

Is it going to put the 68RFE in danger?

I tow a 12k travel trailer, which I keep up on the brakes.

So should the absence of the EB not worth it.

I tow sometimes without it on now.

How long does it take to install?

Will I require a special air intake?

I have a CAI right now.

2007.5 6.7 68RFE
