    So looking at what my next/final step is? What are the pros/cons to going the turbo route or the meth route? Also, anyone have an idea on power? Looking to get near 500/500 if possible.

    My current mod list is:
    SW catted DPs, Ford Racing exhaust w/ 3rd cat delete, MSD coils, SP542 Plugs, 170 tstat, 3bar MAP sensor, XDI-35 HPFP, modified Airaid intake, GH Intercooler, 18+ trans mount, JLT catch can & AJPTurbo E30 tune (18psi and 22.5 degrees of timing)

    Can you currently hold 18psi throughout the RPM range?
    How much are turbos compared to w/m?

    I hold until about 5400. I just purchased a EPP dual intake has that is supposed to help the WGDC by 8% or so hoping to help the boost taper just a bit more

    Yeah especially since you already have the fuel pump. That's already a big ticket item. I wonder how much the 35 can support vs the 60 and if stock injectors have to be changed. I'm sure this has been hashed out somewhere a few times.

    There hasn't been much discussion on the XDi-60 from what I have seen on our platform. We do know that the stock injectors can handle the XDi-35 very well.

    Talked with Uwe, the owner or something of that nature at XDI, and he said that the XDI60 would be appropriate to have with his upgraded injectors he is coming out with. However from my personal experience and what I've seen others with bigger turbos run is just the xdi35 and stock injectors on e30 then the LPFP becomes the limitation. At that point upgrading LPFP then going to injectors and the xdi60 is the appropriate route.
