this really depends on what your after. Tune Boy is the only manufacturer that makes the high rpm maps so if you want the 9k rev then yes. anything else you would only need to have a power commander for wither boost control or if your going to stay with the OEM injectors and need to override the Pulse width ratio of the injectors which is set in the ECU and not accessible. The PCV is a signal interceptor so it can give you more then 80% of the injector.
I plan on going with Lush. For now it will accomplish my goals, and it's more budget friendly. Plus I figure if I want later I can do head and valve work for more power if desired
