Several years ago a friend bought a Fitech for his '68 Mustang with a basically stock engine and asked if I'd help him install it. We put it on with a home made in tank fuel pump system. It has performed without issue and almost no adjustment since initially installed. He has since bought and installed two more. Both of these on fairly wild Ford big blocks and they too have not had any issues. His worked well so I bought one for my car which I have not installed yet. Hoping for similar results.
