I don't know what Kyle is running either. But I sell the LINK ECU, it is a complete plug in replacement, and is fully programable. I sell the ECU for $1200, the remote tuning module for it for $295, and a serial connector for connection to a laptop for $80, this allows to graphically see the changes you are making. I will be running a LINK ECU in my Z around August timeframe. I'm going to start with a JWT and then switch and see how much improvement there is.
