Good evening all you automotive addicts. As you may be aware, GSD is closed and the dyno has been removed.
If you are looking to do power pulls or rent a dyno locally to southern NH/Northern MA, our old DynoJet 424 linked AWD dyno went right down the road. Please reach out the guys at EuroCharged Boston for any dyno services. The dyno is now located at

Very cool Camaro here this morning. Factory Saleen supercharged. Customer complained the car felt lethargic. Dyno doesn't lie, and we instantly saw the issues. Two back to back baselines showed it only making 388whp. After careful tuning, she made a respectable 508whp and 490wtq.
