Can a Predator be used on more than one truck?

I found the MAP Sensor and after finding out by the GM dealer that the MAP sensor is just checking air and it don't have a hose hooked up to it. I put a new one on and now i am getting a P0108 code. what is the purpose of the thing if it is not hooked up to any hose? The code is high input pressure ...

You are right. I was cleaning the one after the filter. I will check the right one out this time. Thanks.

I have a 2001 duramax. I bought a Predator a couple weeks ago and download a tune. It runs great except the P0106 code which is a map sensor. I have a K&N filter on it which i cleaned and also cleaned the map sensor. I have upgraded the exhaust. The code keeps coming back. Any answers?
