2020 2500HD Tuner/Programmer

Miller1 · January 28, 2020

I have just bought my first diesel truck, a 2020 2500HD Denali. The dealership had already lifted and leveled the truck and put 37” Toyo tires on it. But I was just wondering if there are any programmers available for this year model or not? If so what’s the best one overall?

Banks Derringer is at the tail end of testing. Should be available soon.

Your current available option are a few brands of inline tuners (none of which I would offer to my clientele at this time). There are also several companies currently offering direct ecm tuning. I’ll touch on that shortly.

Banks Derringer and Edge Pulsar in-line modules that are currently in beta testing. Both are viable options for those not wanting to go to direct ecm tuning.

The only direct/complete ecm tuning options commercially available at this time are companies using HPTuners software.

In order to proceed this route, the factory ecm must be replaced with an ecm modified by HPTuners to allow software changes. This incurs a significant cost but allows more significant changes than an inline module will allow. Once the factory ecm is replaced, the modified ecm can be “tuned” by whichever tuning company you choose.

Do you happen to know if the replaceable ecm is reversible? As in, can you put the factory ecm back in to retain factory warranty? Or once you swap it out with the modified ecm is that set in stone?

Depending on modifications it is possible to swap back to OEM but if you do dpf delete etc you are stuck with the modified.

Well here’s the thing, GM can tell when an ecm has been swapped.

Basically no matter which route you go, if you have a catastrophic failure and GM feels it’s worth spending a few bucks digging, pretty much all power adding devices are subject to being found. While certain devices do not leave a “fingerprint” in the ecm. There are various ways GM can piece together that more torque was produced by the engine than it can produce from the factory.

Rumor has it that there is an invisible tuning option. But it’s not public ally available. Those guys are pretty tight lipped.

Yeah that's what I was wondering, and assumed.

I'm heavily leaning towards the Banks Derringer route once that is available as it seems like the least intrusive but most beneficial way to go. and very interesting about this invisible tuning option, yeah I imagine they aren't out there marketing that haha.

Just joining the GM HD club and I'm very interested in finding a Tune. I got a 2500 AT4 and I'm wondering if i can make a material improvement to MPG (2-3 would be nice). I'm not worried about the towing side too much as stock has more than enough power for me.

I wanted to see if you purchased the Banks Derringer and if so what benefits are you getting?

Also, does the Banks tune void the warranty? I'm not looking for a full delete at all. Only looking to see if I can squeeze a few more MPGs.

Thanks for any help!

I have been using the Banks Derringer for months now and while it is fun to have more power, it will not improve fuel milage. I dont feel it hurts it either though. What hurts mine is a heavy right foot enjoying the added accleration.
