JWT and JUN are the only worth considering. There are others who can do limited things with the Nissan ECU, but generally not much. One, JET, simply throws a sticker on a stock ECU. This ECU was checked out and it was found that NO code was changed from stock.

JUN is expensive as hell. JWT can almost always give you a dyno tested program for your ECU. Every JWT ECU is tested before it leaves.

Stillen buys their ECUs from JWT.
