Can stack with a TST or MP-8 Pressure box. If your going for all our numbers a TST will do the job but their not the safest box to run. An MP-8 will add about 100hp on the dyno and be fairly safe to run with it but I wouldn't run the pressure box on all the time. They seem to be hard on the injector bodies. But the MP-8 is on a variable knob on the fly.
