    Found it, I didn't hear much of a change at all. So, how do you know you are running out of fuel pump. Does that show in a data log? I have the same Mods as you except the 3rd cat and resonator mod.

    Being on E30 and it being colder here in AZ, I have numerous data logs at different temps. I have had a boost issue for a while now. Brad and I agree it is most likely worn out turbos. My stock turbos peak at 17 ish psi and then taper to 13.o psi as redline approaches at 100% WGDC. That being said. When I added my PPE DP's boost bumped from to 18 psi and tampered to 14 psi at redline. I recovered 1 psi. Samething happened with I removed my 3rd cat and stock resonator. Boost peaked at 19 psi (very briefly) and then tapered down to 15 psi. However, my fuel pressure bombed. I wont go into specifics, but I am not comfortable anymore.

    I can counter with a couple of options. I can have Brad pull back the tune (smart), or I can run 95 or 100 octane to try and recover the fuel pressure while maintaining the current power level (which I want). I am going to source the 95 octane and 100 octane again (which are stupid expensive) and see what my best options are. Maybe even play with some Torco Accelerator as well.

    Long story short, at the beginning of next year I will bite the bullet and buy a XDI HPFP, however I want to get to the track and see what she does as she sits, because I have made a bunch of mods and haven't done anything to see the differences.

    OK, I'm not on e30. I can see where that would bring you closer to being out of of fuel pump.
