Default HELP - P1516 Code After FAST 90/90 Change

My buddy added a FAST 90/90 set-up this past week to his 98 C5and now the car every now and then will throw code 1516 and want to die if idling or go to reduced power mode if running. The problem mainly only occurs if idling in park.

Has anyone had this happen to them? Is the TAC module going out by coincidence?
