Just flashed to stage 1+ 93 v10 this afternoon and after a couple logs saw that my boost was peaking between 7.7-8psi. From what I understand the target should be around 16.5psi. Am I looking at some kind of boost leak?

Theres a shadow 30FF code that pops up along with a 29F3 fuel low pressure sensor code.

Heres a log of a 3rd-4th pull:

Im pretty new to all of this but does anything seem to stand out? Looks like WGDC is a little low but maybe thats because of a leak?

Getting DPs installed tomorrow and ill ask them to pressure test as well.

VRSF 7.5" intercooler
CSF Radiator
VRSF CP / Tial BOV


Thanks!

Indeed! It's probably a boost leak.

I also noticed the low pressure sensor is always 145.1psi Very odd never seen this before, should be around 70psi and fluctuates. Yours is locked in haha. I'd say it's the Low Pressure Fuel Sensor itself.

I will definitely look into the sensor as well. I saw a lot of people getting some kind of low pressure fuel sensor code when they flash their cars with mhd.

Do you think its just a sensor problem if its stuck at 145? Or the pump itself lol

It could be either or. The LPFP sensor is underneath the intake manifold and kind of a PITA to get to. If you look at your STFT it's subtracting fuel due to a rich mixture. If it was a failing LPFP it would usually be the opposite where your fuel pressure would be dipping instead of it being that high.

i have the bov line going from 1/4 to an 1/8 through this little metal adapter that came with the vrsf chargepipe kit. do you think that could be it? I reused some of the factory 1/8" line so it isnt 1/4" all the way through

I would address the fuel pressure before looking for a vacuum leak. You are getting stock level boost and you are targeting twice that. Your WGDC looks fine, it could also just be a tuning issue.
