RENNTECH HAND-HELD TUNER

[stef1808]

Can we get the HHT here or preferably in Germany?
Doing some research and it seems like the quickest and easiest solution to tune my c63

I have not heard about the renntech one but MSL do a hand held tuner which give what you are after. I have no direct experience of MSL
