    I looking for any real world hp gains or 1/4 mile gains to justify the price for the pump?? Also do you have to change the line every time you disconnect the pump to go back to stock for n.y. inspection?? Thanks..

    Why would you go back to stock? Do they do a OB2 scan? If there are no CELS and everything is okay, why would they even think to check the HPFP? Are they literally going to take the cover off, and then take the foam protector off?

    I have heard those new defoulers with cat material in them work well. The rear O2s turned off because of the DPs would be the reason you fail with a tune not the HPFP.
