Trex Owners In Here!
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

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
had this code thrown on my 35th after I installed my h/c .only have the tr 224 cam in it.check for leaks and even swap the map sensor behind the intake.still the same.brought it to my friends local shop and raise idle via ls1 edit.problem solved.hope this helps.will ask what else he did and report back tomorrow night.
