GDE tune for LM2

[kerlyb]

I see Green Diesel Engineering finally came out with a tune for the LM2 motor. +60 hp and +114ftlb torque. Impressive...and tested by EPA to meet standards.

I know GDE has pretty good reputation and following with Ecodiesel owners.

Unfortunately, nothing available for the Tahoe/Yukon platform due to the Global B architecture. I’m sure it’s coming soon - and I can’t wait!

FYI: Tune is not for 2022 with full digital dash…

Has anyone tried the GDE tune on their 2021 yet?

Just FYI - I had a little conversation with GDE and also asked about progress on a tune for the LM2 SUV's. They said they had just cracked the code on the ECM. They do extensive testing on an actual vehicle, so they said it would likely be 8-12 months before they have the SUV LM2 tune available.

On Edit - I had their tune on my EcoDiesel and always had great service/response from them. Their tunes are EPA compliant, but the GM ECM's show when the tune has been over-written and swapped in and out, so there may be warranty implications for sure.
