Bogging down at boost?

[Failure14]

Ok so here lately after finally getting my motor finished
ive noticed like right when i start boosting it bogs down
tremendously but once it gets up to about 7-8psi it stops
and boosts fine....

Ive read alot of threads on here about people with the almost
same problem but they mostly say it bogs down at 8psi+
so its like the opposite for me...

Im running an open downpipe for now, maybe the cat is clogged?
It smells kinda bad when i get out of the car so idk.

Im also having a problem with my ISC valve i believe, maybe
that has something to do with it?

So early boosting it bogs down really bad but then once i hit full
boost its fine...

Any fuel upgrades that could have gone wrong? possible cracked pipes? The vacuum operated valve inbetween 3000 pipe and filter? Just tossing ideas mainly related to air flow.

Nope no fuel upgrades at all, Stock AFM and injectors.

Whats the chances of it being my fuel pump or fuel relay?
Because i dont hear my fuel pump come on when i turn on the
igniton. And before we tried starting the motor and we did the whole
pull efi fuse thing and crank til oil pressure we took off the FPR and
it was straight bone dry, and i tried listening in the
gas tank for the sound while someone turned the ignition on
and i heard nothing....

Once we put the EFI fuse back in and tried starting it then fuel went
into the fuel rail....

right. to run the fuel pump you jumper +b and Fp in the diag block.

try to condense stuff in one thread. you have so many issues going on it's hard to keep track. and some would be helpful info to know as it relates to other things you have going on.

Oh ok?

I tried to put all them in one thread lol but people will normally just
ask about 1 thing and then everyone else forgets about all the other
problems so nothing gets solved... I made a thread on the hose i couldnt
find a spot for and i got an answer within 20mins.

On my 3 page thread everyone kinda skipped over it after awhile and it took
over 3-4hours and i still never got an answer but i got one from my other
single problem thread so its fine now.

Anyone else got any other suggestions or thoughts of why it might
be doing this?
