bad vaccum until car warms up

[justin0469]

so recently i installed an aeromotive afpr. since i adjusted it, the car has kind of a rough idle and almost dies and shakes bad when i press the gas then catches up with itself in a second or two. my boost gauge isnt reading normal vaccum until i get rolling and the car warms up, then it idles normal when i come to a stop.

Sounds like you have to much fuel pressure going to the car. What other mods do you have and what is the pressure set at. As far as the vacuum reading mine doesn't read sometime's in the morning until I am driving down the road either. Common thing.

720cc injectors, 255 pump, cam gears, 6bolt built. without the vaccum line attached to the regulator it was set at about 43spi, it dropped some when i connected it.

it starts ok, then slowly drops rpms til it almost stalls then jumps back up. it does this at idle until it warms up, then idles fine between 750-850rpm

I'm not familiar with ECU+ but did you re-tune after the afpr install?
