Then can we add a boost controller to limit the boost?
The answer is no.
I have a downpipe in my RX-7. Yes, it indeed adds boost,
but actually I don't wanna that much boost that will eventually
kill my motor and turbos. Therefore I put a boost controller
to LIMIT the boost to factory setting, 10.5 psi. However the
rule says the boost controller is not allowed in SP class.
So what do we do? Why can't we use the boost controller
if we are using it to limit the boost instead of increasing it.
