I think I recall reading that the stock HPFP has better tuning capability when paired with MPI vs AT HPFP.Yep, I’m currently running CTS turbo MPI, but I’m thinking about using the autotech pump in addition to the MPI.
Edit: “MPI seems to cause a touch of instability in the high pressure side, so having a stock HPFP makes it easier and more consistent to tune” Hoon 2019.
