I recently purchased a DHP PCM from NightOwl on CLUBGP and started to wonder something about it before I install. Hopefully Charles can chime in also. This guy bought his PCM soon after they were released by DHP. Now sometime in the spring GM released a new code resolving some misfire issues in the PCM. I should know since I was back n forth to the dealership several times trying to figure out the PO300 misfire issue(stock PCM). Then GM released a new code and no more SES since then. Now since this gm code was addressed after the release of DHP how do i know if I have that latest code addressing those misfire issues on the DHP I purchased? The seller says its the latest code but im not sure if he is even sure about that. Not everyone was experiencing the misfires before the gm release came out. There were some thread I remember reading on club gp and charles said the new gm code was updated on his current PCM's. Now if the guy bought this DHP before charles got the latest gm update will I have to pay DHP to get the PCM up to date?
