Boost spiking 20+ psi

[2G Josh]

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?

I would you'll shorten that t25 life even more after 15psi

I just don't understand how the pipe and bov are making it spike so high. Its never done that.

Maybe its just holding boost better, since you had the 2g BOV on before. Just an idea.

That's what I figured man. I'm gonna install the MBC and just go from there.

But my bov was leaking bad at 15 pounds and now the power difference is night and day with the 1g bov at 15 psi.

My gsx just started doing the same thing.
The car feels faster but I know my days are numbered with this t25

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.
