So it looks like this chip is stronger in low RPM, but is ultimately passed at high RPM. Does this affect the top-end speed? Not that I'd be driving that fast, but curious. Also, how does this chip/tune affect CPO warranty and what's the risk to engine, turbos, etc, by making this set-up change? Thx.

It voids the warranty. And yes Benz has to prove the tune was the cause of failure sort of. They will just deny the claim if it’s catastrophic.
By reverting to stock tune, the ECU and can buses log all the reflashes and it’s an automatic flag. And please don’t tell me renntech has a warranty deal with benz.
