That system from Baily still uses the opti for a signal which is prone to failure from moisture. The Torqhead system removes it from the car along with the LT ECU and replaces it with a new balancer/24X pickup wheel and all new modern LS style coils but uses a factory LT1 tune in an LS style ECU. No moisture issues to ever worry about again and you don't even have to remove the timing cover. I'm considering it on our WRL car for additional durability.
