I will chime in with my testimony. I also did this mod about a week and a half ago because my EGT sensor had been damaged from repeatedly backing out of the Godspeed Uppipe Bung.
Worked Perfect. Although I want to add that I had to RESET THE ECU after installing the resistor because the CEL did not go off immediatlely after doing the mod. Perhaps the CEL would have cleared itself after 3 good trips, but it doesn't fix the CEL immediately.
