Did the install today and Holy S#!+ these tunes are as smooth as butter.
The truck has gone from a jerky, noisy, buggar of a thing to drive, with the Evolution, to a smooth finely tuned beast with the FU chip.
In short, I love it.
I pulled my PCM a few days ago to clean off the silicon and then reinstalled it and when I got my chip today I was able to just remove the black bracket and install the chip without having to remove the PCM.
I cut a small piece out of the top of the bracket so it didn't pinch the switch cable but apart from that the bracket is basically still as it was.
