Anyone else experience this? A9L, egr intact, no tab or tad. The harness is m-12071-a50 which eliminates those two. Pro-Flow calibrated to the 24lb.’ers beneath gt40 tubular with accufab spacer and throttle body on the face of it. Cold start idle and flooring the throttle fast are where the car maybe stumbles a little. I did search and got the pull codes message. I even used the exact link you guys put in there and I also ordered the extension cord connection. Oh... and it’s a 351W. I will update with the codes pulled when the scanner arrives, but if you’v experienced something similar post it up.
