These guys are always great. I needed some quick setting changes done on an ECM that was flashed back to stock (2011 Chevrolet Silverado 1500) so I called around and everyone else told me they're booked solid for 3 weeks out. I called dyno comp and talked to the owner, Richard, who said they're booked too but he would fit me in sometime during the day and to just call and give him a heads up the day before. When I went in, I was back on the road in under and hour with the settings changed like I needed. The work was done at a reasonable rate and I fully intend to return when I get a supercharger installed.
