Maybe I should mention mine also has a Brian Leask adjustable control pressure regulator, CIS Flowtech 20% over stock modified aluminum fuel head with lambda removed, and 964 cams timed at 1.26mm intake valve lift TDC before the intake stroke.
It has B&B headers, Garret GSX 61 ball bearing turbo (Hybrid TO4Z) with billet compressor wheel and a very low restriction baffle gutted B&B muffler.
Idle AFR is around 13:1, 3000 rpm steady cruise is around 15:1, and under boost it is never leaner than 11.8:1 and that's with E10 93 octane Florida pump gas.
The front and rear fuel pumps are both Bosch 044.
