yea, but its not good to raise boost level with nothing to monitor, theres a chance it might be good, but probably not, i dont know much about evo's, but i have evo8 injectors, and a 255lph pump, and if your gonna raise it that high, you are gonna have to add fuel. i put mine to 18 and had to add fuel.
