Throttle Response Issue?
I have a new to me 2005 SL55 AMG with about 68k miles. I noticed that while it does have good power the throttle response at certain lower speeds/RPMs seems to be lacking - at least to me. This is my first experience with the m113k engine and supercharger. Not sure if this is just me having higher expectations or if there may need to be something "fixed". There are no codes. I did just install a 76mm pulley and custom tune. The car definitely has more power but throttle still seems a little lacking. I plan to replace the spark plugs and add new wires as they were scheduled for 60k miles but I can't verify if that was ever done. Any thoughts on other things to check in to? Thanks
