[2007 5.9]

I am picking up my truck today from getting a TC/BI and 5"MBRP put in, and I am wondering what level on the SMARTY I can safely run???? I am under the impression that I can run Wild #9 all the time and it should be good....any thoughts????

I already have a VB and an Air Dog installed......

Also is it a good time to break out the 4.2 and give it a whirl????

Your tranny will be the first thing to go..

As you stated above you already have a VB upgrade now get a good torque converter. Ive heard a 48RE with VB and TC upgrade they can take 400-450hp. But remember ZERO boost launches with stock shafts. That should take care of your trans and you already have a fuel system so you should be in pretty good shape.

With the upgraded tranny with billet parts you should be able to handle it. Just don't abuse it during everyday driving. Save that for the track.
