The MassFlo rep was extremely helpful in providing contacts for me to assist in persuading the engineer that I would meet emmissions.....including a contact in the US that met their emissions standard without CATS.
The kit includes injectors, and is very easy to assemble.........even I could work it out.......
Chris will require the details of your intended build to "customise" the tune for you (bore/stroke/cam specs/heads etc). He also sent me the computer file map in case I want to play with tuning myself later.
It was a pleasure doing business and reading the US site blogs there were a couple of cobra owners with exactly my build recipe. They were all very happy with the results.
