Anyone ever experience this. Since my VAFC-II install, I'm having issues with my RPM signal wire to the ECU, but I'm pretty sure this is no longer the issue. It's weird cuz this morning after work it was fine. On my way to work last night, if I got to 4000 rpms, the car acted as if it hit 120mph and cut fuel, once at 3500 rpms it started to rev limit. Any ideas?

ecu is in limp mode.
