2 Different Boost Readings - Bad MAP Sensor?

Did you ever throw a code ?

Yes. A 237 code. Intermittently at first as it was it cutting in and out. Then a constant code when they failed. I could watch it on my scan gauge. The SG reads the map strangely, as in weird boost numbers. At idle it shows about 26 psi and when the map died it would read 14.6 psi. You could still drive it but at greatly reduced fueling.
