mistake ?? you gotta admitt taking a stock clk 320 from 218 to 231 Hp sounds very palatable ... obviously the first issue that come to mind is warranty voiding . I assume it will.... yes ?<br> My next question is is it something you can pop in and out (for those dealership visits )<br> <br> Second is does it mess with the engines set up too much . in sort is it worth while ..<br> Any risks?<br> any thoughts ???
