Cool stuff.
Mitch could you pull up WinPep and graph 4 runs for us and post it?

LT500-87_090 Q2.drf
LT500-87-QV2_025.drf
LT500-87-DCS-6_024.drf
LT500-87-DCS-6.1.drf

Also the correction factor jumps from STD to SAE on other posts. Could you set it to SAE for this graph.
I'd like to see them all on one and not have to jump around. Plus all pipes should be running the same jetting if you post this graph.
That way we have a real "No Smoke and Mirrors No Butt Dyno"
Your pipe does look to make 4 hp more. Thats awesome, nice work. 

Maybe lost in the shuffle but your dyno pull "LT500-87-DCS-6_024.drf" looks like it made more power then "LT500-87-DCS-6_023.drf" that you used for this overlay. The HP gap won't be as big with LT500-87-DCS-6_024.drf
