Best Mid Rpm Power Adders?

[utilityart]

I'm looking to add a little GO to my 6.0. I tow a travel trailer during the summer and I'd like to do some stuff that would help that out. Most of the dyno charts I see for exhausts show most of the gain up in the range that I never run. I try to keep it under 4000 when I'm on the road, so I'm looking for things that would give the best results for real world driving. I really don't care about what it will do in the 1/4.

I looked at the banks power pack but $$$.

Any bolt on suggestions? Truck is stock with 20" wheels. 2007 NNBS 6.0 LTZ Z71 4x4

I'd go for a tune, i hear lots of good things about Blackbear, but i dont have a tune. Ive had an aftermarket catback exhaust and I noticed no extra power or fuel economy, just extra noise. I dont know for sure about these trucks but i used to be pretty into the impors scene, and from what ive seen, 99% of bolt ons just lighten your wallet, especially if your not tuned for them. JMO

long tube headders(not shorties, those do nothing), mild cam, maybe new heads, re gear if you are under a 4.10 and get a blackbear tune. they are the sheet for whatever you want. those would be your best bolt on power adders. starting with headders cam and a tune(or if youre going to re gear do that before you get the tune).
