3 digit numbers for identification:
1 Bar: 039, 460, 883, 876, 153
2 Bar: 886, 012, 539, 609, 701
3 Bar: 749, 861
You can also connect the MAP sensor the truck and turn the ignition to on position (engine off) and look at the boost gauge. A 1 bar will read approx full boost, 2 bar in the middle, 3 bar approx 1/3 of the way into vacuum.
NOPE... the only numbers on the sensor are the ones I posted...
Is there any advantage or disadvantage to running a 3bar on a stock sy????
