As the title says. Just curious. Debating between the MR Diverter valve or an HKS SSQ BOV. Some guy I met was running an HKS Type S bov, took out one of the springs, and he said he never had any stalling problems. He was using an SAFC though.

Thanks in advance!

 

I would stick to the stock blow off valve. Any time you run to atmosphere there will be problems with your car probably running a little rich. Even if it does not stall you are still going to lose some power with something like the HKS.

 

Yeah, I run the GFB Stealth bought from Works. You can manipulate the spring tension(turns) and the venting to the atmostphere. I think since Shiv's new idle update my car has run great with it on. I like it but Smoggy thinks it makes my car run a lil rougher than his. It does do its job holding boost I believe because my car is relatively quick.

 

Has anyone done any dyno comparison to see if you do indeed lose some power with a VTA ?

Also, what idle update are you referring to ?

 

I think he's talking about the new firmware...
