BOV is to release the pressure in the intake/intercooler piping after the throttle plate has been closed to prevent compressor surge.

wastegate however is on the exhaust manifold and opens the dump tube once the spring is under enough pressure(boost) to open to prevent more boost from building and passing through the turbine.

did he ever say anything about blow off valves?

I say go with a manual boost controller if your on a budget.

You are right, I am an idiot who cannot read. I edited it to be correct.

i'm probably going to go with the HKS actuator that's made for the S14 T28.

considering it's rated around 14psi max if i set it alittle below it'll be safe even with a little boost spike...then if i'm having problems with climate variability, spring stiffness, spikes i'll control it with an ebc.

why do people stick with the stock actuators and push 14psi....because it's cheaper?
