Description:

I just recieved a new replacement Racechip GTS Black version 2, as a replacement to my older version 1, which quit working after 4 years, 11 months.  The replacement arrived right after I traded my 17' C43 for an 18' E63s.  It is a complete package with cables.
The Racechip made a marked difference in performance.  I only tested the 0-60 a couple of times, but had consistent times of 3.8sec to 60MPH.  The real improvement is really evident when you are passing, etc.  The Bluetooth "App Control" makes it much easier to change the modes.  This version normally costs $759.00.
This one fits 2015-18 w205 C43.  It comes with a new wiring harness, bypass plug, and manual.  Ebay no longer allows selling performance items that "may" change emissions.
