e) Compressor bypass valves (CBVs) are considered part of
the air intake system, and may be replaced or updated/
backdated independently of the other components of a
forced induction system.
f) Boost regulation systems, either electronic or mechanical,
and electronic fuel cuts referencing boost pressure may be
altered or modified except as prohibited herein. Boost
pressure changes resulting from authorized changes are
permitted.
It appears that as of 2007, the street prepared category is no longer regulating electronic boost control and allows for POV/BOV's. Devices such as the TurboXS UTEC and DELTA systems are now allowed to alter boost in addition to timing, air/fuel, etc.
So, if you run some sort of electronic boost controller and/or a BOV, you can stay in SP as opposed to getting bumped into SM.
