has anyone used a VPC on their NA cars and noticed a difference in power or throttle responce, or anything for that matter?

 

VPC??????

 

vein pressure converter....it takes the place of your OEM air metering device.....im pretty sure it is used usually on highly modified cars that have upgraded injectors or turbos. but i was just wondering if anyone tried it with stage 4 or less NA cars....just curious

 

I believe they are only for turboed cars not NA's. It bypasses or converts your air metering device, to allow your turbos to get more air it is best to use a twin pop system on the car also. I have one but it is not hooked up yet already have my injectors and turbos maxed out.
