Description

From the seller
This is a JWT daughterboard eprom Chip for the 1990 - 1992 300zx Twin turbo with Manual transmission and stock 370cc Injectors. It is for federal emissions so egr and aiv are deleted iirc. The boost jets are also included. Adds 60HP by raising boost, removes the top speed limiter, optimizes air/fuel ratios, and slightly raises the factory rev limiter.
