I recently been having problems with my gts black. my car would often throw itself in neutral and shut off completely. So I'm wondering if I need to get a custom tune for my modifications I have a downpipe, air intake, muffler and resanotor delete. Maybe my car just goes into limp mode, but I've followed the installation process correctly, and even when the mapping is on 0 the problem still occurrs. I wouldn't really recommend anyone getting racechip I literally feel no performance gains whatsoever with this tune
