Worked for me!!!!!I did a write up on how to install a TS chip without removing the PCM.
It's not popular on this site to do it that way, since most of the knuckle heads here can't manage to get it right even if they remove the PCM.
All you have to do is make sure you get the waxy material off the contact points.
I used the scotch brite pad, to remove the bulk of it, and some alcohol on a q-tip to clean it from there.
A small mechanics mirror will help to see if you have the backside clean enough.
I've been 3 for 3 installing them this way.
