Just ordered 2012 CLS63 and need some Dallas recommendations
I am very interested in getting a tune and the Renntech and Vtech ones seem very interesting. I have always done Dinan tunes on all my BMWs and while not the most aggressive tunes I have always enjoyed piece of mind in that they match the manufacturers warranties 4yrs/50k miles.
Are there any MB tuners that also do this? Also, can anyone recommend a good dealer/service advisor in the DFW that is mod friendly. I have one at BMW and always makes things easier.
Thanks for any help
I highly recommend the V-Tech tune. I had it done on my ECU just days after I purchased it. I had the same concerns as you, but rest assured the V-tech tune is well within safe limitations and the performance improvement is tremendous.

I'll post my dyno result soon. You can really feel the car torque and power right after the tune, and just like you I was a little worried that the tune will affect the car's drivability, however three days after the tune, everything function properly, no problem at all
