Psi Upgrade Question

365 Views 2 Replies 3 Participants Last post by  MX-6autox
I've heard things about having a Psi Upgrade done to the 6, the only thing I know is that its something that has to do with increasing how much gas goes into the cylinders or something like that . Could someone enlighten me a bit more on the subject and where could I buy a kit for the upgrade. Thanks.

i assume ur talking about the banjo bolt mod. its a free mod and all it requires is drilling a hole bigger but from what ive heard it doesnt do anything for your car unless its modified pretty heavily and you have a fuel pressure regulator.
