Just been looking around online, been trying to figure out my custom exhaust, and im going to go with a single in dual out to side dumps... but I want to run a exhaust cutout after the downpipe, I have been thinking a electronic QTP but found out about the SP boost activated cutout, which partially opens at 5psi and fully open around 11, now the question is sp says it cannot open fully earlier than 11 psi... well my lightly modded GTP only sees around 9 psi, The gate on the cutout looks like a simple wastegate that opens at a certain pressure so couldn't you fabricate a regular wastegate to open up lets say around 3psi or something, or what would be a good psi to open up at to see the best gains? Can the QTP be wired with a hoobs switch to open and close at a certain psi or will it stay open after because no reverse polarity, SP claimed 36 hp and 30tq gain with this cutout on their turbo car, would it have the same effects on ours??
Thanks in advance to shine light on this topic.
