What could be the reason why I'm getting boost spikes? I'm afraid to drive my car around without having to worry my Turbo will go KaBoom!!! Bad wastegate? Old Blow Off Valve not venting air quick enough? Any suggestions are welcomed. Here are my mods:
*3 Stage Motor
*Trunk Mount Intercooler
*Blitz blow off
*Upgraded JDM CT26 turbo
*Japanese ECU
*ACT racing clutch
*Greddy Exhaust
*HKS Intake
*HKS FCD
*HKS Boost Controller
*550 Injectors
*Greddy Turbo Timer
*Gready Turbo Gauge

It depends. I am not at all certain, but here goes:
1) Your blow off valve is bad/not fast enough/not aggressive enough.
2) Your running rich, or gas is escaping out the exhaust, detonating in the exhause, spooling up the turbo REALLY quickly (WRC cars do this on purpose, but on a street car it isnt good)
I have also read that some mods can actually cause boost spikes (like an intake manifold, or anything like that)
