2008 C 350 Renntech ECU Upgrade.

Just wondering how many of you did this upgrade with the C350?
What are the cons ? (besides that it voids warranty) i read in another post about having to use a certain type of fuel ? im really considering this upgrade after i get my coilovers, but want to make sure that ill be pulling the trigger on a good mod.

Also where would i be able to get Kleeman upgrades in NY

You would just have to use 93+ octane, nothing less. Our engines a lot of the time tend to be de-tuned to allot for lesser octane level gasolines, thus these tunes counteract that by changing ignition timings and other things. Also you can get the shiny renntech badge and show it off lol
