Cant figure this one out. Have a LS1 with a cam, backed by a M6. Cam specs are unknown, bought the motor used.
o2 sensors are both new, knock sensors are new, i tried another reman MAF, and another 411 PCM, and another complete known good throttle body.
Problem im having is that long terms go +25 on both sides, car starts surging and stalling when im off the throttle and in neutral coming to a stop. If I unplug the MAF, everything is fine, it idles better, doesnt stall, and long terms are -8ish on both sides. I dont know what else to try.. Motor is grounded to the body on each courner of the heads, Voltage is reading 14.1 in hptuners. Im attaching the tune and the log..
