The Synapse unit holds 150+psi boost (good luck making it leak), delivers perfect driveability, and reacts quicker than anything I've seen. As for the Tial, it's a fine unit and works very well. However, I really like the design of the Synapse, and it's so transparent that I don't think I'd buy anything else.

Either way, I wouldn't look outside of those two choices.

 

Tial q will take whatever you can dish out. I love mine

 

Toxic is the bov expert..lol..The q is great just make sure the spring isn't to sof or else your check engine light will come on still can't figure out why.

 

COME ON THIS SHOULD NOT EVEN BE A QUESTION!!! THE SYNAPSE HANDS DOWN NOTHING BETTER UNLESS YOU WANT TO CREEP. LOOK AT THE FACTS ITS BEEN TESTED TO 100PSI!!! Put your mind on the well being of your car and dont get another retarded bov ever again!!

 

Are you implying that the TiAL surges? If so, then you weren't using the right spring...

 

Self editted and deleted due to terminal lameness.

 

Tial is the best bov when you find the right spring..

 

does it react as fast as the synapse?

 

with the correct spring yes..

what happens if you're at 1/4 to 1/2 throttle going up a hill? does it surge? or open or close?
my synapse is open, and you can hear the air flowing out of it.

 

Blow's off perfect..I have a bit of a stiff spring and it surges very slight but blows off at the same time around 0 to 4 psi after that nothing clean and sounds like a whip snapping hard..lol..When I had the softer spring in it it blow off perfect not one bit of flutter nothing not even 0 to 1 psi im gonna contact tial tom to see what spring I can use or have them make me a custom one.

 

I have the APS twin vent. Has held 38 psi no problem and drives very nice. Better then I can say about some other bov's I have had or ridden in.

No experience with synapse.

 

Are Evo X bov different from the IX? Stronger?

 

With the Synapse, there is no need to hunt for springs. It works right out of the box.

Neat isn't it?
