What in the hell is going on here???
Ok so here is what is happening. I've had my FD for about two months now and I think I have a small boost leak I'm only seeing anout readings of 15 in./Hg at idle compaired to 22 when i got the car. I bought it with a PFC already installed. I'm doing the silicone hoses next weekend.
Here is the real problem i have not touched the boost settings at all and my boost settings are as follows \
Low: Prim; .80
Sec; .70
High: Prim; .90
Sec; .80
The thing that i dont understand is that the highest reading i have ever seen for boost is .65 according to the PFC while my boost gauge runs as high as 11.5 psi which would coincidently be a reading of .809 if it were on the PFC.
Is there something simple that I am missing here? If not does anybody have any ideas as to what is happening.
My only other mod is a SS DP.
Thanks

those numbers you gave are the fuel cut limits, the % number ot the right in that screen is how you adjust boost. .65 is not even 10lbs boost, so you probably haev somethign ary. 22mmhg sounds a little high for vacuum, maybe did you do any mods to your car since.

I have not changed anything I will see what happens when i get all of the vac hoses changed. I don't get why the PFC says .65 (9.1 psi) when my boost gauge says 11.5. I'm not sure how the gauge could be reading high and it is sitting on 0psi when the car is off so its calibration seems ok.

The power fc and you gauge are reading from 2 different places. Everyones gauge is higher than the Power FC but no one seems to know why. I havent even heard a good reason as to which is more accurate. I just check everything else like inj duty cycle and o2 volt to make sure I'm not lean.
Also, I'm not in my car but think that if your at idle your vacume should read around 15 but if your driving and just take your foot off the gas while going it reads about 22. That is probably the difference

actually...
my gauge and my power fc are actually in sync -
i'm running the greddy gauge, and... it reads in bar.
when my gauge says .5, so does the fc..
