Hi there! Will the UNIVERSAL ADJUSTABLE BILLET ANODIZED TYPE-H RFL PSI TURBO BLOW OFF VALVE be compatible with my 08 WRX hatchback? Please let me know what you think. Thanks!
but in short it may fit your car but since you have a MAF set up the ECU has already figured out how much fuel to mix in with the amount of air is taken in. If you vent to atmosphere you subtract air and the ratios are off. Also no you cant tune a MAF setup to work with a BOV. If you want a vent to atmosphere valve you would need a different set up and its not worth it just for a sound.
If your car is stock just stick with the oem valve (as long as its in good working order) and put the money to getting a downpipe and tune.
W R X, do you want a BOV? Put it on if you do. So what, it runs rich for a nano second when you shift. Learn how to adjust it, make sure it's adjusted properly, hopefully you have experience with a BOV.
