I think my MAP sensor has gone bad. My factory boost gauge reads 6 psi all of the time and my aftermarket guage reads very low like 6 psi even though the car surely has more becasue it pulls hard like it should. I thought maybe the MAP was leaking interally and bleeding off the bosst signal to the guages, but that's just a theory. What all does the MAP control? How bad is this? Buying a new MAP is no problem, but in a small town in AR you can't buy one today and I am plaanning on going to the track tonight. Will this be a problem? Thanks Steve
