s63 Turbo Upgrades
Has anybody in here messed around with the car in regards to the turbos. I'm looking to do some turbo upgrades. Not sure whether it be turbo wheel upgrades or fully upgrading the whole units what my best options are. Car has downpipes airbox and ecu upgrade already but looking for more out of the car.

Here's the thing, even 900+ HP the cars we've done with billet wheels and bigger GT28s don't really run much harder in terms of 1/4 mile- and that's true of all shops. That's why you see "Brand X 7" PKG" of ECU + downpipes + drop-is running 10.8 sec., and "Brand X 9" PKG" with turbos, built trans., intercooler, etc. running 10.7. The transmission controller won't let you get much more power down.
What kind of performance are you looking for? Are you looking for a mile car/dyno queen? If so, you can get there with turbos. If you want a car that is genuinely quicker in the real world, you need to spend big on a standalone engine/trans. controller, or else wait until the TCUs get sorted.

That's what I've seen, but being able to handle the power isn't the problem. Even with those mods the cars are still being limited by the transmission controller.

I use the car to fly around in and am occasionally dig racing the car. I have issues with spending the money for the turbo upgrades if I can't even stall the car up and build boost on the line. The car bogs when held on the stall and the car also already spins which cuts power and completely kills any chance at a good ET. id be happy with a 10.8

It's similar to what we/AMS/others offer. It's honestly just doing work on the dyno, because on the street the TCU is setting the torque limit, so it's not even a durability improvement there. I wouldn't recommend it to anyone on the stock ECU/TCU combination. Stick with ECU, exhaust, maybe some drop-ins and address the intercooler circuit. You should see some great real-world power there.

Not to change the thread subject but may I ask what kind of setup you go with, downpipes, air box...etc.
Good luck...

Renntech, KMB, AMS, Speedriven ... all of us have built 950+ HP Biturbo 63s. My advice would be to call everyone, compare prices, see who you have the best relationship with, and go from there.

Has anybody been able to get this to launch well? Can the tcs in this car be turned off or something? I'm all in for doing it but not if I can only stall it up for a half second before it bogs. It's not practical in real world scenarios

Not with the factory ECU, which is why we've spent the last year+ working on a standalone ECU that will allow full control.

Any timeline on having a standalone released to bypass torque limiting of the TCU? Years ago, I had your TCU programming in my S600. I have a 13 ML63 with a Renntech tune currently which is limited even then by the TCU. I'm taking delivery of a Tesla Model X next month, so I'll be able to finally have the car "down" for a turbo upgrade, but as you basically said earlier, upgrading the turbos doesn't really make sense without a TCU fix.
