has anyone here tuned their GLE43?
I have a 2017 GLE43, I am thinking of the OE Tuning or Renntech Tuning for my SUV. Just wanted to get some feedback from those who have done it and see if the gas mileage has dropped significantly from the tuned?

I don't think you find anyone on here who has gotten theirs tuned. I wouldn't expect gas mileage to change from a tune except from driving it harder. You will probably have to go to find sedans that use the 3 liter biturbo to find anyone with a tune.

Mine is too fast already. Just ask my wife.

C43 owner here. Most of us use the JB1/4 piggyback as it is easily reversible, $400, and happens to run the fastest quarter mile times. I don't believe the JB1/4 will work on the GLE43 though. I would say OE is the best bang for your buck, but Renntech will be the easiest on your warranty if you were to have an issue.
