Good work! I'm still suspicious I've got some fuel pressure issue as I've had to scale the low slope a bit to get the fuel trims close to zero on F6 injectors, when really you'd expect I could use factory F6 data no worries. High slope is fine - actual lambda matches target lambda perfectly so unlikely to be a supply issue. Occasionally stalls if you pull up to a stop too quickly and the trims fluctuate a bit. Have checked most things so have grabbed a GFB reg and gauge so I can check the pressure myself. Mechanic checked the pressure once but complained he had to remove the rear seat so fark know what he did. Obviously neither the supply or return at the pump assembly are an appropriate place to confirm fuel pressure! So I think I've effectively just tuned around some other issue as well. I keep meaning to dig around in PCMTEC to find the table where it switches fuel cut off as you return to idle - if I raise that threshold a smidge I might fix the stall. Anyway, this is your thread not mine [emoji16]
