Mercedes c300 2015

I didn’t think these types of things actually worked though I’m not sure how much horsepower I actually got but I definitely do feel and see improvements! Faster acceleration and more responsive when in gears it’s very impressive! I got the burble pop 91 octane and I love to downshifts when I’m driving it’s amazing highly recommended and if you don’t know how to set the tune up they will help you to a T great staff great product great improvement!
