Mini R60 Settings
 

I am currently running the HFS-4 on MPS with thres set at 2 as suggested by Jeff from Howerton due to a pulse of spray upon start up when I was running in IDC. I do have a number of mods with the berger juice box. I noticed I got a misfire the other day when I bumped up the juice box, backed it back down, no issue. Is it safe to say I should be bumping gain up from the 12 o'clock position? Currently running no restrictor with a .6 jet.

Thanks for your help!!

BTW - Jeff from Howerton is awesome and extremely helpful!

I think using the 0.5mm restrictor is recommended. When you are bumping up the boost, the system should inject more automatically. But if you were hitting the fuel supply limitation, it may be necessary to bump up the gain or bigger jet.
