So I just installed a uicp and a 1g bov. My car was at 15 psi from bolt ons and the bcs mod but now its spiking past 20 and always past 15 but creeps and stays steady at around 14-15. Should I install my MBC? Should I worry about the car kitting 20 psi for a second?
 
If you are spiking to 20 psi, what does it settle to?
It sounds like you are experiencing some creep and a mbc won't do anything for that...
3" straight piped turbo back can cause creep especially on a stock turbo. The wastegate is not able to bleed off enough pressure/exhaust.
There are threads related to boost creep.
