Peak AFR's of 12.3/12.3 aint "bad" as such. I would prefer a little richer (11.8ish) but theres alot of other factors.Afr's look a little laggy coming onto boost but this could be the technique the tuner used to load it up on the dyno.

From then it descends to just at the top of the 11's from 3700RPM on. I didn't ask him to lean on it hard for mine, I enjoy power and some element of reliability.
