BUT If you get a new PCM from Intense, then it will need to have the crankshaft variation relearn completed so the stored/learned value corrrectly matches the amount of error that exists in YOUR car. Most "trade grade" scan tools can do it. So it doesnt have to be a dealership. Look for shops that say they can do GM SPS (Service Programming) as then they likely have the neccessary experience.A lot of shops will have a minimum flat-rate charge for this type of scan tool service. (doesnt matter how long it actually takes) Sounds like your quote was a minimum 1hr. I would keep looking. Maybe try a few smaller private AC-Delco shops, which should have the necc scan tool, capable of doing the crankshaft variation relearn for CASE
OR
Find someone in your area with HP Tuners as it's scanner mode can do the CASE relearn on any LSJ

It really depends on how they decide to modify your tune i.e. direct edit or reflashing your PCM with HPT using "calibration only" vs. "write entire" options etc etc)

A CASE will not be required if you send your PCM in ahead of time and WILL need to be done if you get one from us initially (along with a security relearn).
