MSP with FCD past 10 PSI Safe

[b00sted]

from what i understand, all msps r different. some hit fuel cut at diff psi's, i know mine was hittin it at 10psi, but a buddy of mine boosted 13psi with no fc or fcd. so i dunno, best bet is to get ur engine prepped up for worry free boost

I've been running 17psi for 2 years now with the help of additional injectors. A/F ratio hangs steady around 15.

I was running 10psi daily with no problems and out of no where BOOM! I checked my comp weekly and never saw a diff. So knock on wood if your boostin past 8psi on stock internals. Hope that helps.

If that is true you have one freak of a car. That a/f is way to lean. Are you sure you meant 15??

Yea with basic mods and maybe tuning, I would say 10 psi is pushing the limit of being safe. I'd say 10 psi is around 95 percent safe with supporting mods.
