On the DOHC setups, the blue box trims map voltage to allow the use of 310cc injectors, has a boost limiter cut setting so that the ecu never sees boost, and pulses the injectors longer for additional fuel. The sohc blue box that comes with the 92-95 kit does the same except for trimming map voltage for larger injectors.

No you wont. I would recommend an emanage rather than the blue box.
