Random Stalling Help

[wortho32]

hay hope someone can help with this I am a bit stumped.

I have an r32 gts-t with an rb25det s2 coversion.

since I put the motor in has abnormally been stalling like it is running out of petrol I have a 22 month old walbro pump running off 12v and seams to be working fine.

at idle its fine when you put you foot down it just bogs down like it is running on 4 cylinders than just stops could this be coil pack related?

car is stock standard just fmic and straight threw pipe.

Start with afm clean, check/replace plugs, check rail pressure, check timing, check fuel filter... just as a start

Pump needs to be wired to alternator voltage, it's a known fact walbro's don't like the factory fuel voltage switch setup, nor were they meant to be run at 12v either.

Try a mates afm to test

do you know what boost your running? cause i remember when i got a FMIC first put on without a tune, the boost rose from 12 upto 15psi and when that happened it was like running on 4cylinders...

Going to try an afm tomorrow and coil packs

How many volts is needed for the fuel pump it is wired direct from the battery.

Running 10 psi as I have an standard r32 turbo on it with no boost controller
