WOW another person here in St. John's!!
There are a few shops around here that I have had a CSVT worked on:
TJ's Place - Excellent work, but you'll pay for it. Mostly does imports.
CPR Service - Good work, has a reputation as a speed shop, but will do any kind of work. They installed my Accusump and gauges.
Cabot Ford - I don't really recommend these guys just because of the price but if want to go to a dealer these guys are better than Avalon Ford. I myself get a discount though and the service is pretty good.
Good luck, and if you need any more info let me know!
