I had a Kleemann ECU tune on my last benz and loved it. I am unsure about this Kbox upgrade but the numbers look good. Does anyone have any feedback on this product. If it's trash I prefer renntech. I appreciate all feedback. Thanks in advance

Really? You'd pay like $2,300 for a 40 hp ECU tune from RennTECH?

Personally if I'm going to go with an ECU tune, I'd go with AMR...

I gotta go with the more reputable Mercedes mod company. Renntech kleemann brabus, for me the money does not matter as much.

I agree with MassC450.. AMR is pretty reputable in the German car scene

AMR is the best !!! I had renntech and it was junk compared to AMR.. Renntech was barely noticeable!

I am going to have to agree with everyone above me. I have a stage 1 AMR tune on my C43 and it is unreal. Best bang for your buck performance modification on the market for this platform. I would recommend 110%

Anybody here running an AMR tune in the Los Angeles Area?
