I have a problem that I can't figure out. I have a 2007 GXP. 27000 miles on it. I'm not getting any information on boost. I know I have the power, because I can feel it. I just don't get any readings on the boost gauge.

I vaguely remember that this could be a symptom of one of the MAP sensors not providing readings(?)

I see you have GMPP tune. Were your T/MAP sensor connections soldered, or still crimped? If the latter, get them soldered - that might well fix the issue.

Here you go

There are 2 MAP sensors (Manifold Absolute Pressure): one located on the cold charge pipe (driver's side of motor) which is actually a TMAP because it monitors both pressure and temperature, and one located on the intake manifold. The DIC gets its reading from the TMAP located on the cold charge pipe. Try unplugging and re-plugging the connector to the TMAP and see if that helps any. Otherwise, it could be a bad sensor.

Is it worth just getting new sensors? I threw a code while on vacation and took it to a GM dealer. They pulled the sensors and sprayed them with cleaner. Could that be the problem (letting someone else touch my car. LOL)?

Do you have an aftermarket Cold Air Intake? If so, its the oil from the filter fouling the TMAP sensor....

They cleaned the T/MAP sensors? Really?

I think you mean the MAF (mass air flow) sensor in the intake, not the MAP (manifold air pressure) sensor that's after the intercooler. I'm guessing the MAF is what the dealer cleaned too.

MAP sensors rarely go bad. Just check the connections. Get them soldered if not already. I'd lay money that's the issue.

Yes...sorry. It was the MAF sensor. I don't have any oil on the cold air intake.

Do you have a pic of what should be soldered? and where its located.
