So I have a 2016 Silverado 5.3L 1500 High Country with a K and N series 77 cold air intake and a Borla ATAK cat back Dual Exhaust and I am looking for the best/recommended tuner to go with.... Really I just want overall better drivability comfort and power, disable the speed control limit and AFM disable functions. After some research that I have done I have noticed multiple mixed reviews and could not decide which one to go with. Here is a list of the ones that were most talked about and was wondering if any of these would best suit my truck or if there is something else out there:
Bully Dog 40417 GT Platinum Tuner DiabloSport 9245 Trinity 2 EX Platinum DiabloSport 7220 Predator 2 Platinum Superchips Flashpaq F5 Tuner
Thanks in advance!!
Has anyone used this PSI Power Tuner or found where others have used this? I found the product on two different sites; the 2nd URL has better details on the product. I'm skeptical on this product, being that no other tuners have released products for the 3.0L Duramax (LM2).
PSI Power 2020 3.0L Duramax Performance Module (Truck Edition) | Thoroughbred Diesel
Agricultural Diesel PSI Power Module 2020 3.0L GM Duramax (parleysdieselperformance.com)
Also, what about these two products?
I have a 2020 GMC 2500 AT4 Duramax Diesel. Fuel economy is normally 18-20 mpg local and 21-25 mpg highway. I've noticed multiple times that if I completely fill the tank up, that my instantaneous fuel economy and average drop significantly. Instantaneously runs about 8-12 mpg and my average over the last 50 miles drops down to 11-13 mpg. Then suddenly after about 25-50 miles of driving, it will jump right back up to good fuel mileage. If I never completely fill the tank, this doesn't happen. Dealer says they've never heard of this, but I don't trust dealership feedback. Previously I had reported multiple times that DEF fluid levels were completely wrong and erratic and they said there were no reports about it. Then miraculously there was a software recall that fixed it.
I have a 2003 Chevy 2500hd 6.6l diesel. All gears and shifting were working fine. Pulled out on highway today and had to get on it. When going through gears I heard it slip up and rev as if it slipped out of gear. I slowed down and got off road. It seemed to be stuck in 3rd gear. I tried putting it into reverse and it would not work. The shifter doesn’t even feel like it’s moving into gear when I move into reverse. When I move shifter to Drive, it sounds very rough and it starts off in 3rd gear. The truck will not shift out of this stuck gear, not even go into reverse. Had to put home slowly in that gear range. Need some help, What’s going on?

I have a 2001 2500 HD with ZF6 6 speed manual transmission 4*4, I bought the truck at a deal and am finding out why......it's a unicorn...lol. I am just a blue collar worker like most of the rest of us and can't afford the $3500 price tag on a rebuilt trans especially since I don't have a $1000 core transmission to trade them. I still have the transfer case and driveshafts and all other parts to the 4*4 trans..I found a 2wd ZF6 6 speed trans with only 140,*** miles on it I can get at a steal and am wondering if I can change tail shaft and make the 2wd into a 4*4 transmission? Any help would be greatly appreciated even possibly part #'s if possible.....I guess I can drive the truck as a 2wd if I have to but 4wd is one reason I bought the truck....BTW this is my first diesel so any and all help is appreciated.....
ONE I WILLIE
