Bolt-on LS1 with TH400.. dyno results

Motor has never been opened up. Mods are as follows: Clear lid, QTP headers, True Duals w/ Dynomaxx mufflers, Tune, FTI TH400, FTI SST converter. I have no idea what the stall is, it's somewhere around 4000. I had it built for the spray so it's pretty tight on motor. Can't really complain with the results:

Good numbers through the TH400. Was this on the nitrous tune? AFR looks a bit rich.

I guess you could call it a "nitrous tune". I don't change it when I spray the car. And I hit it with a 150 shot. I could probably get a few more ponies out of her N/A by leaning out the tune, but I'd rather just stay conservative for the nitrous. I usually throw in some 100 octane at the track too.

I just went 12.21 @ 110 w/ a 1.7 60'. I use to go 1.60-1.62 consistently with the 4L60E but usually with the same ET.
