Going from stock to BD Power Super B Special

Hi All (and my first post!)

I have a stock 2007.5 6.7 with a DPF delete, EGR delete and using the XRT Pro on the first power setting. Automatic Tranny and I tow a 9000 pound RV.

My stock turbo has a malfunctioning exhaust brake and I am thinking about going to the BD Super B Special Turbo kit that comes with the two piece exhaust manifold, special EGR Hardware and down pipe.

Is anyone else running a similar configuration and will this kit from BD work well for towing AND daily driving? Are there any pitfalls like not spooling while going 55, getting too hot, etc?

What is the Special EGR hardware? Is the manifold that comes with this kit good?

Thanks!!
