I spoke to one of the technical people for about 20 mins about everything haha
F9 is lean, not rich. I suggest you speak to one of the technical team as opposed to the sales staff. F9 on my car yielded an actual AFR in the high 12's as verified on a RR using an independant wideband AFR. It is only a target AFR though, EGT protection routeine will dump plenty of fuel and give you a very rich mixture if it gets too hot. Why not check it yourself, run it at F9, then log specified and actual Lambda, then try F2 and log specified and actual Lambda again.Got to love Meth though, being able to run the Boost at 9 and Timing at 7 at Stage 2+
