Do the purging and priming as instructed in the user manual.

That's done. Anything else on the board? Like the MAP sensor?

Good. Map sensor can be tested by moving the TRIG jumper to MPS later on.

Give me an update what you have done so far, such as system prime, purge and TST tests on page 11.

On top of my head, got it all setup (wiring, purging, IDC jumper, gauage scale to 100% which is one bar away from full bar)

Running two 1mm nozzles, both atomized well. Was wondering if theres a restricter inside already or do I need restricter? Boost are target to max 21 psi mid range so far because of the 2.5 bar sensor, redline will drop to 15 psi or less.

Enjoy exploring the system for best performance. HFS4 has lots of options.
Restrictor is unnecessary.

Hi Joey

I have recently jumped the bootmod3 ship and never got my JB4 to run properly so thinking of going the same way as you.

Did you finish your installation? How does it work - please share

Move the IDC jumper to MPS, let me know it it triggers the system.
