What is the best tuner

[Matthew McEwin]

I just purchased a 2021 6.2L Silverado and I started down the upgrade rabbit hole. I initially started reading about getting an AFM disabler to prevent future lifter issues but then I figure if I'm spending $200 for a disabler then I might as well spend a few more bucks for a tuner/programmer that does that and more. My question is what (in your opinion) is the best tuner/programmer currently available?

Only 1 tuner available and that’s through HP tuners and it pretty pricey!

 

If you want to change some settings on truck than the new Pulsar LT is available. It allows you to turn off DFM, auto start, adjust throttle sensitivity, and speed limiter, along with tires sizes and gear ratios.  
 

I’m interested in the Pulsar LT but waiting till spring to see if they get the bugs/kinks worked out of it and crossing my fingers that HP tuners will lower their price a bit.

There is no tuners as far as handheld items.

 

Only way in is HP Tuners and they only support 2019 and 2020.  No support for 2021.  $1400 for the ECM swap plus $500 in HP Tuners credits plus whatever the tuner doing the work will charge.
