    Hobbs Switch, Boost Activated, Boost Level Adjustable: atpturbo.com

    Add one of those to the boost pipe and set it up so when you have 2-3 lbs of positive boost your fuel pump controller switches to high speed mode

    leaving the boost reference off the FPR gives Allen a better chance at tuning the engine by mail because the FP is constant and predictable. Adding the HOBBS switch to the pressure side of the intake just cranks the fuel pressure up to ensure you have plenty of fuel going to the rails to help match the additional air that is in the intake.

    You already have a Hobbs switch that was installed with the billet fuel pump voltage boost module?

    Put it as close to the intake as possible in the cold air pipe. I'm not an expert on boost at all. I just know how it works. I've never had a boosted LSx engine that I've built so I'm not really sure what the solution is but I'm trying to analyze what's going on and what may fix it.
