These units are the predecessor to the Borla units. Company went into receivership, was owned for a short period by one of the casting suppliers then purchased by Borla. Years ago, Borla would rework the units to bring them to current design. Typically the shafts, bearings and blades were replaced. Original design had major air leaks by the throttle blades.
You might contact Borla and ask if they will bring them to current design. Doesn't hurt to ask.
Regarding the ECU, that part of the system is Junk. To my knowledge, no one was ever able to make it work. I've had good success with Performance Electronics, others have used FAST Xfi and Holley Terminator. You need a higher end ECU as the less expensive models don't have the necessary settings to make it run.
