Shifts hard and drives good with mine. Only negative so far is the TC lockup is being a little funky. Like trying to stay locked up too long coming to a stop, and locking up too late when leaving from a stop. Hopefully it'll clear up over time.

Just wanted to give Zerocat101 a quick "thank you" and shout out. I received the TCU in a very timely manner. I just installed it today, and it is a marked improvement overall. The transition between gears feels quicker, crisper, and more direct. Predictability is improved as well. It lends itself to a more connected feel to the car, if that makes sense. Two thumbs up. Thanks Zerocat!

Zerocat - this TCU tune also works for a SL55 / R230 (2004) with the 722.6 trans yes? Car is 100% stock. Assume its plug and play just like on the E55 / W211's ??? Seems pretty awesome improvement with the trans even on a stock car.
Also when ordering for a SL55 / R230 (2004) should I order the gearing option as 2.82 which is what i "think' my car has yes (i'm all stock)
Is it best to go with the Stock WOT shift point if my car is fully stock or one of the other options 6700/6800/6900? I'm gonna order one of these if you can help me nail down those Q's thanks very much
Thx
