The TTFS XDI pump is holding 20-21 psi the whole RPM range on PS2 turbo. This is only on 93 octane
Still dialing in the setup, we just started upping boost and damn the car is a missile! This is a nice setup for even pump gas setup. Once we start throwing more octane at it (ethanol mix or race gas) we can bump the timing up more aggressively, but trust me the car is quite fun as is
Here is my setup from this morning - 20+ psi at 6.5k rpm on 93 octane pump gas - fuel pressure is perfect.
