Default BEGi fpr question

Just finished my bandaid system. Instruction from BEGi says that pressure gauge should show you 28-30psi at idle but mine showing 40psi, whn Im pulling signal line it shows 47-49psi, so what is a problem? and wideband all time showing different numbers sometimes it 12 sometimes 15.5?????

Wow.

AFRs, through my very unprofessional experience should be ~15:1 at cruise, maybe a little less, ~13.0-12.5:1 at tip in and 12:1 in boost, less depending on how much boost.

Pics of how the FPR is routed.

You can adjust it by backing off the nut and threaded portion on top of the
Begi unit. Loose = less pressure if I remember correctly.

Yes you can ajust it with nut, but it won't go lower than 40psi with signal line in

I mean with signal line off gauge read 47-49psi, so thats numbers good follow begi instruction. But when you put signal line back on fpr it reads 40psi but begi manual says that it should be 28-30psi. And a wideband goes so crazy. I started car today and at idle number was 12.5, yesturday night time was 15.5 and early same day was around 12
