well my car runs peak boot at about 22.5 then it tappers off....and my map sensor would always read 20.5 so it was about 2 lbs less no biggie but all of a sudden last week my boost is still 22.5 but its no reading 14.5 big diffrence......its off by about 8lbs now.....i dont understand ..... im here in miami FL it did get really hot and sticky here all of a sudden but should that cause that much of a diffrence in pressure reading??? or did my sensor take a crap.....its reading 8lbs less than it should all the way to redline....any feedback?

 

any one?

 

Yes, if it's a GM MAP sensor. Their quality is not that great.
Hope you still have your receipt.

 

actually i dont...........grrrr gm crap

 

is that cause of a leak or did the sensor just flip out?

 

If it's a leak your boost gauge would also be affected (showing less boost).
What kind of sensor do you have?
Is there any way to recalibrate it?

 

its a gm map sensor .....no way to recalibrate and no my boost guage has stayed the same

 

I'm hoping you can help me. I need help installing the Gizzmo launch control interface to the ECU colored cables. where does each color go? Please help me.
Thank you very much,
Johan
