i like blitz alot.
but mikes tial is pretty nice also

 

I like my Tial very happy with it. It did suck when i first got it casue i also had a 7psi spring and it ran like crap due to it staying open when ideling. but now that i swapped it out i am happy and love it.

 

If it is going to leak, it will most likely hunt for a solid RPM @ idle as well. A Tial with a proper spring is not going to leak under any circumstance either since it will have positive manifold pressure (that is equal) pushing from both the vaccum hose side and the diaphragm side. Once a Tial has the proper spring, it will never leak due to its design. Everyone has the HKS, my last and next SR will have a Tial. Redneck engineered in the US of A.

 

i had a HKS SSQ on my supra ...it was actually pretty loud but sounded very nice, probally get one for the SR , have also thought about Type S , but everyone has that..Type RS any good?been seeing them pop up alot
