ECU flash or dyno tune at Benzworks
I have a stock (k&n filters) 05' E55 with 56k miles and want to get it tuned at Benzworks. My understanding is the OE tune they use is right on and without mods would probably work just fine. However, my OCD says to get it dyno'd to make sure the tune is perfect. Worth the extra $$? Your thoughts and experience are appreciated.
