The Flash Says: “We realize that not everybody has access to a full service machine shop, so we offer some machine shop services to our parts customers. Feel free to call if you need anything, and we’ll do our best to help you out.”

Testing and Tuning

Dyno Tuning Cad Company offers a full range of dyno tuning services for all of your Cadillac performance needs, with our state of the art multi-channel Dyno-Max dual-head water brake engine dyno and in-ground eddy-brake chassis dyno.

Engine dyno services start at $600 for the 1st day (including hookup) and $500 for each additional day. Tuning options include EGT, WBO2, programmable ignition advance from the control console, and a wide range of other tuning aids.And, of course, we always have a wide variety of high performance Cadillac engine parts in stock, if you would like to try different parts on your engine to see the results.

Chassis dyno services start at $100 for the hookup and first 1/2 hour, and $50 per additional 1/2 hour. Tailpipe WBO2 is standard, and a full range of other optional tuning aids are available, as well. Our chassis dyno bay includes a 10k Lb 2-post lift, 36″ roller wide enough for duallies, drive-through bay, and tie-downs / space for FWD and RWD vehicles. Parts changing, etc is available for an additional charge, or you can bring your own tools (and help, if you like) and do it yourself.

Hosting for chassis dyno events, such as charity and club day events, is available on Saturdays by special advance arrangement.

Other Services

Custom Mounting Bracketry We offer custom bracketry design and fabrication for special applications. Custom work is billed strictly on a time-and-materials basis, and requires a non-refundable deposit. Options include traditional fabrication (bending and welding) and CNC machining. We normally work in aluminum and steel, but other materials are available as needed, such as stainless steel. Due to the nature of our business and the unpredictable nature of custom work, lead times can be extensive when our shop is backed up with regular work (which is often).
