Kleemann or RennTech upgrades
Anyone out there done a Kleemann or RennTech upgrade?
I've got an 2003 CL6 and I'm trying to determine which brand to go with.
Powerchip is the cheapest at $2,500 just ecu not tranny upgade.
(Seams reasonable priced)
Kleemann seams to be the best from what I've researched (size, history ect.)
Renntech smaller, American company.
Any thoughts?????

More information
After 2 weeks of doing my research, I found out that Evotech writes the software for Renntech on the 65/600. 
As quoted in the article;
Quote "Still, software revisions developed by RENNtech's Hartmut Feyhl in conjunction with German software wizard Evotech increased boost from the nominal 14.5 psi to about 18" Unquote

And a couple of MBworld members have informed me this information is valid.

In my opinion, the TCU upgrade is just as important as the ECU upgrade. I went with Renntech through AdamG. Very happy with results.

Does any one know what size turbos are in the 600/65? What is the stock boost on the 65 and what is the boost after the ecu tune?

Was told by Cory that tuning the TCU can be difficult due to differences in every car. Is this a common issue, or something specific to Kleeman? I like that AdamG has a good reputation, but I feel more comfortable going with a reputable company that I can hold more accountable if something screws up. If this were my john deere, it may not matter as much
