erractic fuel pressure

[xms]

Okay so i put in AFPR aeromotive kit from lipp installed and it was fine, today i installed the walbro 255 high volume high pressure now my guages bounce but when i start to boost it steady is this something that i should be worried about?

Does it bounce while idling or while driving?

It should bounce while driving obviously...

Well the pressure was nice and steady till i put in the new fuel pump 255 high pressure high volume then it became really erractic?

do you still have the j-tube restriction in the return line?

is your vac holding steady on your boost gauge?

if you remove the vac line from the afpr does it still bounce?
