Has anyone in the New England or New York Metro area had any experiences working with J & M Motorsports in Manchester, CT (specialists tuners)...Spoke w/ co-worker who has a Mustang who claims they also work on Vettes...looking at the website they claim vette experience. I'm looking for a good tuner. I'm about 60 miles north of NYC. Also seen "vette doctors" located on Long Island but don't know anthying about them either. Anybody any good/bad experiences. Thanks
