THE RATTLE IS NOT TIMING, BUT RATHER PRESSURE.

THANKS 2 R EPA WE NEED MORE TIMING TO MAKE THE CR RUN MORE EFFICIENTLY,WHETHER 4 MPG OR POWER OR JUST DAILY DRIVING.

TIMING IS REAL KEY THOUGH.TOO MUCH TIMING AT LOW REVS IS NOT SO GOOD.

TIMING AT A LITTLE HIGHER REVS R GOOD 4 MANY REASONS.

1-BETTER MPG
2-MORE POWR
3-CLEANER COMBUSTION
4-LOWER EGT
5-LESS SOOT IN OIL
