[King Nothing]

Whenever changing the cam size you should always have the tune checked and adjusted before replacing other parts after a swap. That might have been the issue the whole time. But if that’s not it, seeing those Christmas tree lights would bug me too. The Christmas tree lights happened for me 3 years ago, but when mine did it my tach and everything stopped working and the only thing that would register was speed. My car wanted to almost die when taking off or between shifts (M6) It was because not only was my battery shit, but I needed an extra ground. I replaced the battery with a gel battery and did the extra ground and haven’t had an issue since.
