If you are running Procede, it is better to let it control the water/meth flow and onset of failsafe.

Both HFS4 and Procede reference load as prime flow control from multiple sensors. Procede controls flow from raw sensor signals compared to HFS-4 reads composite Fuel injector signals as well as boost and fuel rail pressure. Both methods are very competent performers.

If you are running a flash tune, let the HFS-4 control the flow and failsafe.
