2004 gmc envoy_sle
i plan on getting a pcm tune from pcm4less. i have spare pcm from a wrecked envoy from work, the thing is both of the pcm's are out of a 2004 envoy, which have the problem of having to be reflashed with the lastest software. my plan is to send in the spare so i have the original from my truck. i know i will have to get a CASE relearn, has anyone had a problem with getting the relearn done?
