Trex Owners In Here! Got a ? Any one with the TRex cam having probs with the MAP sensor throwing codes? The heads are FFHP 1 and have been milled 12 thousands. Could the cam be causing lower manifold pressure? I am at a loss here

This has me puzzled.. Any suggestions as to what it might be? I have replaced the sensor and chased the wires as far as I could.. Any thing I might be missing?

You said you were running milled heads with a Trex? I thought that cam was too big for any milled head without flycutting your pistons? If you have a PtoV issue, a bent valve can cause you to throw that code. That's way out there, but it will throw a Map code with a bent valve.

After some research, this looks to be a common problem on the 02 vehicles with larger cams. AP is going to adjust the 0106 table and we will see if that clears the problem
