For anyone looking for the easiest to install performance “plug and Play” upgrade. You need to consider this. I have the Eurocharged TCU and now the LM21 Upgraded TCU. This one is better by far, hands down. I’m sure there are other upgraded TCU’s available and I’m sure they’re great too but this one’s amazing. What a fun new toy.
Last image of the season. Certainly NOT
Valk Quality background but, I was smiling all day.
On the strength of this fine recommendation, and due to my wonderful experience with the paddle shifter kit (which I think is essential!), I went ahead and bought the TIeken/LM21 TCU upgrade to replace my Eurocharged version TCU. Why spend all that money when I already had a decent TCU upgrade from the laughably horrible stock Mercedes TCU program? It's to keep me interested in and happy to keep the beast by bringing it up to modern specs while keeping it as pristine as possible. So what do I think of this TCU? The shifts are even smoother, and they are faster. That makes me very very happy. Thanks for the recommendation!!
