I am from Nova Scotia, Canada and am interested in a HPT...I'm not sure if there is anyone locally on the east coast of Canada that can do any tuning for a 2000 s/c LD9...if anyone knows someone in this area could you let me know...I am looking at a tune, but right now the only place I have found and contacted was a place in alberta called westers garage (or something like that, and I don't know what software they use for a tune)...if anyone has some suggestions that would be awsome.
I would get on HPtuners forum and see if they have a regional section that shops post in. Or look for a dealer close to you and call them. Another option is to call GM V8 dyno shops near you as a lot of them use HP tuners and see if they are willing to look at your car.
