half boost

[bendraptor]

hi all newbie here,

I have a gen 3 raptor with jb4 tune, intake, add intercooler and snow methanol kit. recently I noticed its running at half boost only getting 10-12 psi and it's definitely down on power. I have no codes. any ideas what it could be I checked with a local shop and they weren't much help because no codes. I did data log it and I'm leaning out to 10.7 on afr so I was thinking fuel filter or possible pump. figured Id reach out to see if any one has experienced this and might be able to lead me in the right direction. thanks in advance

Welcome to FRF.
Pictures. Or you’re losing boost on a prius

it sounds like you may have a boost or vacuum leak here.
Did it always exhibit this, or only after a certain point?

10.7:1 is extremely rich. Most likely you have a boost leak; not uncommon after charge air cooler modifications. Double check all of your connections, sometimes they’ll appear secure but will leak under pressure.

First thought was boost leak.

I had one and I felt like I was driving a v4 ecolooser.

Who did the install of the parts? Go back and double check their work.

Guaranteed a boost leak.
