    A TD04@21psi flows a lot less than an 18G@19psi. The 18G will cause more strain on the transmission.

    doesn't feel like 14 psi going to do a few things to the car like exhaust intake and go up with the boost a bit.just doing some research to see what the automatic tranny can run safe with. thanks for the help any more info please pass it on
