Best Tune for GLC63
So many to choose from...
Looking at Renntech but it is $3000 and 601HP.
My wife said she saw some up to 900HP.
I have the AMG performance exhaust - what is the best tune I can buy for $3000 or less that makes the most HP, easy to change back and forth and of course not detectable once you remove the tune?
Thanks!!

I have Eurocharged tune with Renntech downpipes. The tune definitely woke up the car and is an OBDII tune so you can flash back and forth. With Renntech's, you will have to pull your ECU and send it to them.

Renntech now sells an OBDII dongle (no need to remove ecu), I have the + version, suspension module, bov & bmc filters. This weekend I installed their exhaust controller which opens valves 100% all the time! They are also showing turbo and fuel system upgrades up to 767hp but that's a little over the top for me. I'm hoping Akrapovik will come up with an exhaust.

People need to understand that unless you track the car, max HP/TQ values are somewhat irrelevant when it comes to tunes. The big advantage of a tune on street cars like ours is the shifting of the torque curve lower, and the increase in throttle responsiveness. Driving my Eurocharged GLC63 around today I can say that response is absolutely telepathic. It takes off like a Ramjet missile at any speeds I am realistically driving at, helped of course by the AWD. For when I really want to go slow, Comfort mode is always available.

+1. Looking at getting a tune for my 2020 GLC63. Not looking for crazy power but a good increase without killing longevity is the key for me.
