2010 E550 COUPE
Just tuned my E550
Hi i just got a renntech tune with waranty for 1600$
But they said it would gain around 20whp but not dyno proven.
So i took it on the freeway and it seems the same under 4k rpm and first gear. 3rd gear it feels quicker then my brothers 911 s, but not like 20whp faster i feel ripped off lol.

Race your Brother's 911S and see what happens; if you raced him before you can compare the gap, maybe it will narrow and you'll have some kind of indication?
I do agree, w/o dyno proof it's all subjective.

2014 E550 4Matic with P1/LED/Pano
I had a Kleemann tune on mine and reverted to stock. Didn't feel the difference was worth the money....it changed the car but not necessarily improved it. Kleemann was a class act and we worked things out to our mutual satisfaction. Can't ask for more than that.
