Can I safeguard against boost spikes with BOV?
Question for all the techies out there:
I have a Greddy Type-S BOV and am going to an AMS GT3071 turbo kit. Is it possible to limit max boost by purposely setting the BOV spring tension so that, for example, anytime I hit more than 25psi boost, the BOV will "leak" and therefore will help to control unexpected boost spikes?

I want to be able to use my XEDE for boost control, especially with the introduction of the SMART auto-tuning feature, which includes boost monitoring.
I figure that by purposely introducing a boost leak at a certain PSI, the BOV should help protect against overboost.

Sorry perhaps I'm using the wrong word ... I know that I will be able to hold boost much better with the AMS kit. Which is why I'm trying to safeguard against a situation where suddenly I see 35psi being pushed because of [insert favorite reason here]. Point-in-case: AMS Evo during the OLA, and Shivs WRX wagon a couple of weeks ago. Maybe overboost is the word to use.

I wouldn't say with a bov. I'd say through other means like tuning. Using boost-cut, fuel-cut, ign-cut, or maf-cut you can limit what the engine sees in terms of airflow or boost. The only way a "bov" would work is that you would have to use a wastegate and actually weld it on the intake pipe. I've seen it on some turbo drag mustangs.

Widebandphilip, I hear what you're saying and I dare say that with the XEDE and its new "SMART" feature I will probably have all the electronic protection I can get, but if something fails (boost solenoid goes haywire, SMART gets stoopid, or God knows what else), I'd like to have a mechanical means of relieving pressure in the system.

he is saying if his electronics go haywire....going to another xede map won't help
ive seen it on a supra before, guy blew his motor because the EBC took a dump and he his 35psi fast like on pump gas.
BUT, the way the xede works.....it manipulates the solenoid so i can't see that ever happening....worst thing i woudl think is that if the xede quit working you willl be running off the wastegate spring(or slightly higher if you bleed) and that won't be more than 20 psi or so
