I am running up to just under .9 bar of boost, is that too much? (esestially do I need a boost controller, or is it unnecessary unless I want to specificall limit my boost)

my mods:
Apexi PFC
PFS SMIC
PFS intake
PFS DP
RB cat-back
Efini y-pipe
blitz boost & temp gauges
& uber cool custom battery mount

 

.9 is perfectly OK as long as you have the fuel to cover it. Since you have a PFC, that shouldn't be a problem. By the way, doesn't the PFC control boost? I always thought it did.

 

it does control boost. I am assuming the base setting is for .9 bar, cause that is what I am hitting. I have read that it isn't the greatest boost controller out there (can spike etc) so I was thinking that I would get a profec b or blitz controller to handle the boost.
