UPS Stall 3000 TC upgrade for C55

[Mr Fixit]

Some advise please. I want to change the TC on my C55 and have been looking round, the UPS stall 3000 gets good press. What is the implications of changing, has anybody done it, are there alternatives and whats it like to drive when the TC is changed.

I've always thought that Mercedes generally know best and are generally smart cookies as matching a TC to a car can be tricky so i'd like to know what the difference would be against stock and especially a new OEM part.

Secondary cat and res box removed, Euro-charged chip

Cheers

You mean UPD stall? Good if you race your car and do regular quarter miles and vmax runs.

The 3k stall is OEM in sense that it's based on another high torque Mercedes TC - usually one from a diesel. If you can weld you can DIY it for next to nothing rather than import one sold by them.
