Ugh, I have search and cannot find a clear answer to this simple question. Some say 14.7, but that is more than a stage 2 pushes... How much boost can stock MAP handle?

 

The stock LSJ TMAP hits 270.59 kpa at 5V. That is equal to about 24.74 psi. That is not to say the sensor will just give up at 5V. That is just as high as it can read.

The most the PCM will ever be able to process is 255 kpa or 22.48 psi, so the stock sensor is more than sufficient.

 

Thank you!
