    Easy solutions for returnless fuel systems?

    I know this has been covered a bunch but my exhaustive searching has not presented me with a clear solution.

    My 2010 Sierra Denali has a Whipple kit running. 8lb of boost with 60lb/hr injectors. Obviously, with the returnless fuel system, I'm seeing less than 50psi pressure delta at WOT. My IDC is at 95% at 11.45AFR.

    Is converting to a return style system the easiest solution for boosted applications? Has anyone done a write up on exactly whats needed and how to get it working? I've heard so many conflicting stories on what works and doesn't work that my brain is fried! After all this time, I had hoped that the aftermarket would have come up with a simple solution to the stock FPCM. Whipple includes an MSD pump booster with the Camaro kits, but MSD says that it's only for return style fuel systems.

    I guess I was just trying to be lazy and hoped that someone already did the R&D so I don't have to get knee deep in some project that is over my head.

    Thoughts?
