All depends on how you set your regulator... You can always modify the oem venturi to connect to it.
Can you explain more?
How exactly can I modify the oem venturi to work properly with this?
Wouldn't I set the regulator at 72psi? I thought the whole point of the product was to get rid of the oem restrictions and not need to run a return line from the front of the car.
For the cost of it running a return, external fpr off the pi fuel rail, etc. Seems less expensive. I am kicking myself as that is what I wanted to do up front and 'do it once and do it right'.
