will a profec B help to control boost spikes?

still having trouble when second turbo comes on, it spikes to 14-15+ pounds at WOT. will a profec B help stop this or do i have to get a PFC first? i cant really afford 1600$ right now for a PFC with tuning, so i was thinking the profec B might work fine for now?

If your car is indeed spiking. THe boost controller will be your fix.

The PFC controls boost but from what I hear you still need a boost controller on top of that. It has something to do about how the pfc controls it and somehow it's not effective at it. I've read it before but since I don't have a PFC nor do I plan to control boost with it. I didn't store the info on my permanent file directory :)

I control my boost with a PFC and so far I have no problems, but for a cheaper fix, yeah the profec B would be the route to go..
