What spring should I order with my TIAL BOV? 7,9 or 11?

LOL, Do you have a boost guage to know what kind of vacuum you have.

I do but the car isn't running at the moment. I’m getting ready to install 19t’s.

I'm sorry....I can't remember what we went with it's been so long ago.

blow thru or speed density, get the lightest one to keep the BOV cracked open at idle and the fastest response (this is what the synapse bov is)

I'm was thinking we went with the lightest as well but because of how it responded with the ATX.

AFAIK the "11" is a 10 on the Q tial valve.

Depending on your vacuum it may be a bit tight. I'm running a "9" right now and about 19-20 inches of mercury of vacuum. It doesn't seem to leak at idle, but I'm probably going to swap to the "10" to be sure it doesn't leak under heavy engine braking.

There is a seller on ebay that has the springs cheap if you end up needing a different one. I may also have a 9 for sale soon if you want to order a 10 and try the 9 later.
