OBD tune
Anyone come across an OBD flash tune for the 2021 GLS63? Renntech doesn’t have anything yet for the new engine. I’ve seen one flash through Eurosports Performance tune (up to 720hp). I’be tried to contact Renntech but no answers. They have a tune for the E63 that gets 779hp out of what I assume is the same 4.0 bi-turbo.
Anyone ever dealt with Eurosport? I know renntech is a quality tune. I had one on my ‘17 S63 and that thing was BEAST. It’s a shame Mercedes leaves so much untapped potential in their motors.

I spoke with RENNtech a couple of weeks ago. My guy said they're shooting for end of the month to release their OBD tune. They wouldn't give me any numbers but when I asked if can expect similar to other 4.0 engines, they gave me a round about answer to yes. Obviously the other 4.0 don't have the EQ Boost so, I think that's what they've working through.

We have an obd tune for it as well and have tuned a bunch of them.
just be mindful your car is equipped with a cpc and you will need to tune that as well. Make sure your shop can do that or the tune is not worth it as it will handicap ya
