 About NED&T

New England Dyno & Tuning is one of the fastest growing dyno shops in New England!  To better serve our customers, we have evening hours for those who cannot make it in during the day.  Being in an easily accessible yet secluded location allows us to dyno as long as needed without interruption!

We have a full-time, knowledgeable staff ready to help our customers.  If it's a custom tune you are looking for, we have well-known tuners that come to our shop and work on vehicles of all types. 

New England Dyno & Tuning is owned and operated by John Sansoucy.  John has his Bachelor's in Science, Manufacturing Engineering and Masters in Management from WPI.  His passion, years of experience and vast knowledge of automobiles along with his background in Engineering are the perfect combination for getting the most out of your vehicle. 

From hot rods with carbureted engines, newer performance vehicles with fuel-injection to trucks and everyday vehicles........we are able to service them all! 


1200 HP - 200 MPH Dynojet Dynamometer

Our Dynojet Model 248E Dynamometer is the very same used by Winston Cup NASCAR Teams. With our Dynojet Dynamometer, you can quickly and accurately measure, record and diagnose performance problems. By simulating the best "seat-of-the-pants" road test right in the shop, problems are easily diagnosed in a fraction of the time.

Our Mission

To treat our customers with respect and provide them with the best service possible. To continue to grow the business, to provide a wide range of services and to meet the needs of our customers.
