Mods for 2014 GMC 2500 6.0 with .410 gears?

Best bang for the buck is EFI live tuning from Blackbear. I have 3 tunes installed on my 09. Wakes up the 6.0 on standard 87 oct fuel. I have th 87-89 performance tune, tow tune and 93 performance tune. I generally pull with the tow tune, or with the standard 87 tune. I have used the 93 tune a few times empty and seeing what its good for... that tune will leave both tire marks down the road if you want... lol. People ask well what do u get with the 600.00 dropped.....well u get rid on most of the TQ management for one. Second u do truly get better fuel mpgs...Third, your 6.0 gains 25-35 hp, and depending on tune.. 40-50 lbs of TQ. is it worth it? Yes. I drive the truck conservatively, don't hot rod it, don't need to. I have increased fuel mpgs by 1-2 on both city and hwy. it's not going to pull like a diesel, but it will pull and drive far better from the detuned factory setting.... I don't have any other mod on my truck, don't need it. The GM 6.0 will really wake up with a cam change, but I'm not doing it. I've worked on LS engine for a long while. They're one of the best ever made. I like them better then my 350 engine for sure. I can tell u that in the 6.0 your power is stronger after 3k, rpm. The so call VVTI kicks in, peek TQ is found around 4K rpm. The nice thing about Blackbear performance is that Justin won't tune it to destroy it. Reallly a great guy to deal with. When u order, he sends you a scanner, you connect it to your truck and run it in for about 1/2 hour. It records the engine parameters and you email him what it recorded. Then he ask what do you want tune wise and he then send you and email back with the custom tunes. You download it on your scanner and then to your truck. Very easy and lifetime tunes! Check out there website, I think that's the best bang for the buck. Sorry to ramble on with the post, tired from last night working. But always up to help out answer questions. Let me know if you have any other questions.
