## Discrepancy

AFTER 464.6 HOURS, THIS CONTROLLER SPLIT IN 2 PIECES, RENDERING THIS PART USELESS AND CAUSING BOOST TO FALL OFF IN THE INTAKE MANIFOLD.  IT APPEARS THAT DURING MANUFACTURE, THE HOUSING FOR THE SPRING WAS MACHINED TOO DEEP ALLOWING ONLY ABOUT .0312 INCH METAL HOLDING THE PART TOGETHER.
