that's not remotely accurate.
.
a BOV has ABSOLUTELY NOTHING to do with boost pressure. period. it rleases excess boost when the throttle is closed to prevent back-spinning (surge) on the turbo compressor wheel.
a boost controller can NOT lower boost below the spring in the wastegate. it only goes up from the spring, and in general, a BC can do about double spring. So, a 5psi spring is the lowest, and about 10 ish is the highest with the controller for that spring.
on a 10 psi wg spring, you can go to about 20 psi via the BC.
To the OP, Yes, you will need to re-tune.
ok nice tnks for shredding me heheheeh, the bov I kind of knew but i wasnt sure the word "backpressure" kept hitting my head while I was writting but the boost controller, well didnt know, so u couldnt set a lower pressure with a boost controller then the spring pressure on the wastegate u say?
I don't really like the manual boost controllers because of the knobs trying 2 guess on how far 2 turn them.. But either way I'll have 2 retune?
To the OP, Yes, you will need to re-tune.
