Looking to add an ECU upgrade to my E550 4Matic. Stock power is great, however I wouldn't mind picking up a little more along with possibly some improvement in MPG. Was considering Renntech or Kleemann for ECU. I called to MB dealers in the Chicago area and both told me they no longer deal with Kleemann due to issues they experienced. Does anyone have an opinion on ECU options? Also, any recommendations for tuners in the Chicago area?

Thanks!

Not much action in this section.

There was some discussion here: https://mbworld.org/forums/e-class-w...h-my-e550.html

There are a few people who tuned their 550 motor in the CLK section.
