Getting some Brabus work done on my G55 soon(B55 performance kit)...
My question is should I get the Renntech or the Kleemann ECU upgrade?
Kleemann claims more power, but I like the fact that Renntech advertises the +2 mpg with a conservative HP gain, especially on the G55's MPG on the highway.
I would like to take the G55 to the DuPont Registry's car show here in Tampa, and I wouldn't want to embarrass myself
