recommendation on 156 tune?
 

Drivability, reliabilty, sane pricing, good service..who?
Thanks for your help....

I only have experience with Eurocharged but I am happy with their tune, service, price, and drivability.

:y

Only 2 people have a tuned cl63?
 

I'd like to use that new Renntech setup, but 2900! For just ecu changes? If I use how does that work? Do I send them the box, or...?

You can also look at E63s, CLS63s, S63s and SL63s. Same motor tuning on different platforms makes no difference. I'd search a little more, you will find Eurocharged has had very good success on the V8TTs and a much more user friendly price than Renntech. When I drive my car I realize they know a thing or two about the V12TTs as well.:zoom:

Agree.....
 

but the non turbo 156 is pretty lazy in the 216, that's why I was looking particularly at that combo...but sounds like they are good folks..

Not too happy....
 

Not that anyone will see this on this board, but....am I out of line? My shop has been waiting a week now to get the file back. This is after I made a shop appointment to let my guys install it, out of an abundance of caution.That's when, after waiting most of the day to get it back, they told us that "uuh, the guy that does those I don't think is coming in. Maybe Monday." So that weekend was lost, now we're another week out and still no tune....anyone else had this kind of aggravation?

I sent mine to Corey at kleemann. 1k 3 years ago.

Definitely changed the car.
