    So a couple of weeks ago, I finally finished installing my fully rebuilt 6.0L LQ4 with LS3 heads, custom CAM, 2014 Camaro intake/fuel injectors, shorty headers, and 4L80e transmission.

    New TPMS Sensor Reset Help Needed

    I had a bad TPMS sensor on my right front tire, and when checking the DIC I would only see "--" for the tire pressure. Since one went bad, I felt the other 3 could go at any time, which would be my luck if I only replaced the bad one. So I bought a set of 4 new TPMS sensors off of eBay. These...
