I was cleaning off an old hard drive and came across this article. Does anyone have any idea about it's source and/or validity?

By "tricking" the ECU, the timing can be advanced in the M2. To do this, the Crank Position Sensor (CPS) must be moved. There is not enough adjustment capability built into the stock CPS, so it must be modified to permit the adjustment. This is done by enlarging the mounting hole on the CPS with a Dremel tool. When complete, the stock timing of 9-11 DBTDC will be changed to 14 - 16 DBTDC. The steps involved are:
- Unplug the CPS and remove the undercover and CPS bolt.
- Remove the CPS.
- Using the Dremel tool, enlarge the bottom side of the CPS mounting hole/integrated washer by 2 mm to 2.5 mm (0.078 - 0.098 inches) in order to gain the upward movement in the CPS.
- Re-install the CPS. The gap between the pulley plate teeth and the CPS should be between 0.5 and 1.5 mm. Torque the CPS bolt to 69 - 95 in/lb.
