Overboost Annihilator vs Boost Pressure Relief Valve

[bears4x4]

which is better?Overboost Annihilator mod on my truck, or Boost Pressure Relief Valve fromDiesel Innovations - Products
what are pros and cons to this, which is a recommended mod

[Pocket]

Relief Valve creates a boost leak at higher boost levels in order to fool the MAP sensor. The Overboost Annihilator regulates the boost pressures to the MAP sensor without creating a boost leak. I went with the OA since it doesn't create a boost leak in order to do its job.

well there is actually 3 types- sp diesels electrical version, a regulated version like itp's,
and a valve like dieselsites.there is a lil back and forth, about which is best.

dieselsites works just fine. the boost leaks are un-noticable, and have no effect on performance..were talking about needle point hole leak. never heard any problems with them.

the itp seems to be slightly more popular. But it has its qwarks too, most of the problems are, user error install problems. at least a half dozen or more have been sent back...really because the user got the ajustment so far out of wack, and needed dennis to reset it. so if you get that one and order on the phone I would go a head and ask him how much you should adjust it , and when . they seem to work fine when set up correctly and not toyed with.

sp diesels has the same one user had no luck with it and bashed it with a hammer, personally i would have returned it for a replacement, or a refund...others use them fine.

kinda boils down to price, and prefernce.
I would wait to add it, to a list as they are small and can be shipped easy with other things.
as far as preference that is an individual user opinion.
