ML55 performance chip upgrade?
lol. thanks guys/girls!
PM me if you want the price. It's a fantastic chip and it's usually one of the first mods people do to their cars.
Something else you want to think about is getting a better set of air filters to improve the engines breathing capabilities.

Here's the really cool thing about RENNtech, a LOT of dealers are RENNtech authorized dealers as well, but the ones that aren't, know what they are anyways. Most dealers are friendly, but just incase you do encounter one that will reflash your ECU back to stock, just tell us. We'll take the proper information and verify that it's your for your specific car, and we'll reflash your ECU back to RENNtech standards
