Like the title says...maps ECU to 16PSI and allows 7500 RPM. Asking $200 shipped economically to your domestic door. This solders to the board, but I found a socket and soldered that in instead, making the chip swappable. I'm in MN (still). I also still have a spare tranny for one of these cars. We never ran it. It came as a spare with one of the cars. Open to offers on that. --Erik Lawson
