is this 91 or 93 octane? if it's 91, that's a bit richer than it needs to be with that timing. if it's 93, then it's a lot richer than it needs to be.

on CA 91, i can usually run 13-14 degrees at peak torque with an AFR of 11,5:1 tapering to 11:1 at redline (usually around 22-23 degrees). on 93, i usally run about .5 points leaner than that and a few more degrees of timing.

max load in 3rd/4th was 2.5/2.6 g/rev
peak boost as mapped was solid 16 psi at 3300 RPM holding until 4800 tapering to 12 at redline
timing was 11 at peak torque rising to 16 at 4800 and increasing to 23 by 6800. (91 octane)
fueling was 10.9 at boost onset tapering to 10.6 at redline.
load looked like a bookshelf from 3600 to 4800.

Just wanted a general "that sounds about right" or "that's all wrong" from these numbers. I would post up a log but I don't have the notebook here.
