your fras are rock solid and as good as factory - no problem there.
your rkats - idle trims - 1.9% and 2.3% - are higher but well within the 4% spec. idle is where a small vacuum leak will make itself most apparent but, as you say, they seem to be sorting themselves out. for comparison, my rkats were/are:
.32% and .28% with the larger throttle body but with stock maf holder and tune. this tells me idle is not thrown-off by the larger TB (which i had thought might happen given that idle is based mostly on throttle position and a larger TB will let more air through at any given position).
2.5% and 1.8% when i moved over to the 996 tune. rock solid at these numbers and within spec so no issue. due, i think, to the fact that the ecu is trying to tune for a 3.4 engine but only moving 3.2 litres (again, my understanding is that idle is mostly throttle position and not maf, so air not being metered). but then, trims would be negative in this case, so perhaps i have an air leak too?!?!?!?
