It is not necessary to use the restrictor if your are running two 1mm jets. It is better to leave some upper ceiling in case you want to increase flow via the controller.

It the circuit is not already pre-configured from your suppler, you need to do the following:

Stand-alone on flash tune:
1. Set the MPS solder link to "2" (2.5bar map sensor).
2. Set the CEL to DR1 to prevent CEL if you are using the on-board boost cut unpon failsafe activation.

Procede Piggy-back:
3. Set the "Threshold" trimmer to 12% (fully counter clockwise).
4. Link "DFS" to disable failsafe activation since Procede takes care of this.
