Putting on Speedwerx full exhaust and PCV and was wondering if Autotune was worth it. Does it actually monitor/control each side of motor? If running PCV can you rely on Speedwerx map and be safe or do you have to run the A/F sensors and gauges to be safe. Bro in law has same sled and setup with 1700 miles with no problem but I know they don't all work the same.
