The Best of Mercedes & AMG




what's the bottom line on this?? YES or NO ?
any dyno chart to prove the HP gain ?
does it work for 5.5 AMG and 6.3 AMG ?
lol alot of question...
thanks guys
Of course- It makes your A/C feel better when you use the foot setting and makes the rear seats more comfy over 63mph!
Seriously curious, what other benefits would you ask out of an ECU tune than performance in a perfect world?
