Haha, ya those old probe turbos are crazy sleepers, i had a buddy with one with a t3/t4 setup with no tuning done and he smoked my 300+hp AWD DSM like it was standing still, they may be ugly but they are definitly fast, but only because they have a mazda engine under that junk ford shell!
Please help!! HKS SSQV BOV Install..

Funny i also had a leaky power steering and had to have the dealership fix it. so if you get the recirc cap you can run the hks in vta cause i would LOVE to run mine in VTA but i dont want to have the car run like ass either
yeah I also lost my key so I just ordered one from eBay...damnit.
And yeah if you get the recirc cap the most problems that i've seen are an unsteady idle, which i don't even notice. And a couple backfries every now and then. But the whhhooosshhhh when you drive by an Evo is wayyy worth it

HHHHMMMM how is the shifting when you run vta? I heard that shifting becomes rough because your rpms drop quicker

the car does run richer venting open, this is true. there are tuning solutions which work around this.

well i went ahead and ran the hks in vta and capped the recirc and my idle is fine and i do get a backfire here and there but not as much as i thought it would. Also i've noticed that shifting from 3-4 has become a bit harder dont know if it's the blow off valve or it's just me. I do think it is well worth it for the awesome sound you get from it in vta. i mean what is an hks without the whistle?
Installing a BOV is not a good idea, do any of you guys know what that is doing to your car besides it sounds cool?
You are venting metered air, this is a big problem.
Let me explain a little...
The MAF meters the air coming in sends that voltage to the ECU so the ECU can make the nessecary fuel trims. The stock turbo system reintroduces metered air into the system post-maf avoiding metering the same air twice. Basically it recirculates it. If you are putting a BOV on your car you are blowing that metered air out the system before it gets in the motor and thus making the mixture way rich. It is really an uncontrollable situation that cannot be tuned out, only a bandaid tune. You would have to use a blow-thru type MAF to measure the air post-bov to run a bov. Since the MS6 uses a draw-thru type MAF installing a BOV onto the car is not a good idea, installing a bypass valve is the only option.
Just FYI.
