Its well known in DSM land that a 4294 will be good for around 40psi, anything over that and its a dead end.

This is where the 4202 shines, before ~38psi they are about the same. But the 4202 will keep making power above the 40+psi mark.

I would monitor fuel pressure and see how bad its dropping as you up the boost. Then if you need more fuel pressure a pair of Walbro 400lph pumps would be my choice over a BAP.

Okay this is more really good info. If I can swing it I was thinking about going to one of fp's HTA4294 or hta4205 is what they call it. Otherwise I have a decent deal lined up on a 4202
