Modification to make the GLK 250 a little more fun and exciting to drive
 

Already have other fun modes of transportation as it is but I'm curious to see and hear of what (if anything) I could do with our GLK aside from a tuning chip (which has varying opinions, pros, and cons from my other thread.)

Any suggestions or ideas?

Consider taking this opportunity to share what you have done to your GLK.

Thanks in advance.

Just enjoy the plain boring way to get from A to B. GLK doesn't like being rushed.

Mercedes doesn't leave a lot on the table when it comes to squeezing more performance out of their engines. Plug in and bolt on stuff may have bad consequences. Be careful. Typically the chip sets "fool" the ECU and expand the engine limits to get more out of it. As you might expect, this could lead to early failures. These engines are not like early GM small blocks you could do almost anything to for more performance.
