2013 SL550
Weistec retune
Newbie here. I just purchased a 2013 SL550 with only 13k miles. It’s basically brand new and I love it. I want to thank everyone who posted here as it greatly helped me identifying upgrades to my new ride! I had the ECU reflashed by weistech, and the power is exhilarating. Actually “chirps” the tires when it shifts to second gear. Noticeably much faster acceleration. The car has plenty of power anyway, but at only $1,200, why not? It’s ok to splurge on yourself!
