maft-pro + HKS SSQV BOV install question

[kmckiness]

Hey,

I am having the Maft-Pro installed in my car with a new HKS SSQV BOV with the upper hardpipe kit.

Will I still need to use the HKS recirculation kit if I run the maft-pro in speed density mode so that my AFR does not get screwed up and run richer?

I have the recirculation kit but I was not sure if it was needed to install if I am running in speed density mode.

Thanks,
Kevin

in speed density, no. you can run open vent w/o any problems since the map sensor reads after the bov. unlike stock where the air reads before the bov and then open vent you loose that measured air causing a rich condition.

Cool. It looks like I can just keep the recirculation kit off the car then.
