Tow Vehicle

[Broke Pilot]

Oh, and as to the original question about a box or ‘canned’ tuner like Bullydog... please please don’t do it, for many reasons.
First off, most times their power increases are on premium 91/93 fuel. So now it costs you an extra $1/gal every time you fill up.
Super chips and hyper techs programming doesn’t like Chevy computers, tends to fry them after a year or two. I have a great relationship with the rebuilders here in Houston after all the computers I’ve put in chevy trucks lol
Bullydog won’t admit it, but on some tunes to show any gains I’ve actually seen them turn off the knock sensors to inhibit a CEL on their low octane tunes so they can crank the timing up.
Biggest problem with a box tune is no truck/engine are the same, your engine might like to run a little rich to make power, joe Blow’s truck might want a touch on the lean side. With a canned tune, your elevation may be different than where Bullydog or Xxx tuner dyno’d their tunes and then you’ve negated the tuner all together. I’ve seen trucks lose power on the dyno with them.
I know they’re quick and easy, but if you’re gonna tune it, pay a shop to do a dyno AND street tune with EFILive or the sort.
But first off, I recommend gears... lol it’ll drive like a new truck, and it’s gonna be way more noticeable than the 20-30lbft you ‘might’ get out of a tune.

And Larry isn’t wrong about the cam, but now you’re still just burning more gas to get where you want to be.
The factory 6.0 cam is about as good as it gets for towing. Go with anything much bigger or more duration and you’re gonna shift the hp/tq curve higher in the rev range which isn’t necessarily bad, but it’s harder on parts and now you’ve lost true low end power. Plus with any ‘towing’ cam in the 6.0, unless you throw a set of headers on to let it breathe that extra fuel burn out the most you’re probly gonna see is 15-30lbft under the factory curve and a few more than that peak.
The 6.0 truck heads don’t flow well comparatively speaking, so there’s also that choke point you’re gonna be fighting.
