I’m new. I actually don’t own a Camaro or firebird. I do have a 2000 Camaro 3.8 fly by throttle and 4l60e. This is installed in a 1980 Triumph TR7...2 weeks ago -
Not much going on, replaced my Kenwood double din stereo with a Pioneer double din, the Kenwood had problems. Then replaced my power inverter for my reverse...2 weeks ago
