Which is the best? I like what I've read about the Vortex but hear a lot about the Diablo so I'm not sure which one to go with. What kind of features should I look for it to have or whatever, I've never messed with anything like this and know nothing about it so any and all advice would be greatly appreciated.

Your truck doesn’t use a “chip” it uses a tuner via your obd2 port

Yes, Diablo is one of the better hand held tuners.

You buy them online. And plug them in yourself.

Oh the custom tune I do myself? Ok, I'll check into it and from what I've read across several sites is the Blackbear seems to be best. Thanks y'all.

Ok so I contacted black bear, the way they do things seems straight up and simple enough. Just hope it's affordable enough lol.

A custom tune is worth considering also. One popular option is Blackbear.
Thanks for the recommendation, I contacted them so I'll have more info shortly. They seem pretty straightforward and simple, I like what I read on their site. Better than diablo, that scared me some. Knowing me, I'd go in and tweak different aspects and fry my engine. That's why I was wondering about someo e else doin it.

Does the same thing as black bear using the diablo tuner. And is a bit cheaper if I remember correctly.

"We can disable the evap and rear O2 sensors however that may be in violation of the EPA's Clean Air Act so we can only do so on off-road vehicles. We will need an affidavit signed and returned to us certifying this will be used for off-road use only." So this is the email I received, part of it anyway, from black bear. What do I do? Just lie and give em an affidavit or what?

That's their legal disclaimer since disabling any emissions control devices is illegal for on-road vehicles. The affidavit is absolving them from responsibility. If you are nervous about doing this, you might be better off trying to find a local tuner that can do it with HPTuners or EFI live.
