Headers and Tune affect reliability?
hey all, posted the other day, but i am 90% sure i am picking up a 09 C63 with 70,000KM on it. (roughly 43,000 Miles i think)
my question to you people is how do headers and an ECU tune effect reliability?
the headers are from Agency and the Tune is EuroTune.
does this cause any added strain i should be aware of?
