Quick update:
After I was tracking down a leak on the PS setup - I saw that my bull bar was was looking like crap.
I took the 4 bolts off - and removed it. I really like the looks of it without the bar on there.
I also decided to ditch the Bro-Truck billet grill. I removed it but the plastic grill underneath looks like crap.
So I painted it with SEM Trim black paint - and will put it back in when it finishes drying.
I also installed the LBZ mouthpiece and updated my 10+ year old cold air intake.
The truck came with an AFE Magnum Force intake - which doesn't look like it has been in production for a long time.
So I found a Spectre Diesel filter that fit in the AFE box - and put in the LBZ part.
I can't say I feel a huge difference - but removing a big restriction in the air path has to help.
Now for the pics:
