Steve! Good to hear from you. The ECU is set at 6500 but the TCU will be at 6400 and that's where it'll shift. Currently in my car is an Evotech TCU with a raised limit and I've been banging off the limiter with no ill affects, so far. My thinking goes like this. The valves in our engines are tiny and on the light side so that's a plus. I read the MB forums and it seems quite a few over there are red lining at 6800. I haven't seen a "blew the motor" story from the raised limit. Then I start thinking about how many cars I've owned that lasted over 10 years. If it blows after a while I'll find a nice Porsche or CL65, but I think the engine will endure despite the extra rpms. If anyone knows of a blow engine (3.2) with a raised limit I'd like to know about it. I could be playing with fire. Perhaps I've convinced myself otherwise erroneously.

Steve, since you know the guys at Buckhead could you ask them their opinion?
