How do you measure WOT performance while street tuning?

I never thought to compare HPT to the LS2 torque spec. Factory rating is 400 ft lbs, generally a Mustang dyno shows about 25% less than the crankshaft.
That would suggest my C6 is 300 ft lbs stock, the modifications suggest maybe 10% improvement. Don't know what improvement there is in the tune.
This car is odd in the fact were the AFR ended up. I did try moving the AFR up & down.![Bang Head](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_banghead.gif)
Would like to go back & try increasing the fuel in the KR area's if the street shows the same KR. I don't think the road will as this dyno seems to load a bit more than the street.
Also I need to compare the torque delivered to the street as well.........4th gear WOT from 2000 rpm to 6200rpm. I've already had a warning from Buford this summer so I best be careful.

So this is a street log 4th gear just like the dyno run.
I have not analyzed the run so be careful what you read into it.
I really wanted to compare Torque Delivered from the dyno to the road test.
I'm not running a WB as I was using the NB location for that. Difficult to add a bung for a WB with stock exhaust........
