New best in the 2500HD
Met up with Dewmanshu, Breeze, Holty, Beastmode, Sharpshooter, and Slownlow4.8 yesterday to run our trucks at Mason Dixon Speedway. Oh yeah, DC_Justin even showed up this time......with his T/A though. 
It was a pretty nice day and a great time.
This is the first time I've ran the HD with the TVS on it. I ran a couple passes with the 3.2" pulley which is around 6.3psi or so. The best with that pulley is below.
60' - 2.033
330' - 5.715
1/8th - 8.799
1/8 mph - 79.66
1000' - 11.455
1/4 - 13.720
1/4 mph - 99.12
Then I decided to slap the 2.8" pulley on to try for some lower times.
The first run with this pulley I had some rev limiter issues on the shifts because I had raised the shift points to 6000 rpm and didn't change the 6000 rpm rev limiter in the engine file. 
Anyway, here it is.
60' - 1.959
330' - 5.577
1/8th - 8.581
1/8 mph - 82.16
1000' - 11.153
1/4 - 13.354
1/4 mph - 102.38
I never got anymore clean passes do to rev limiter/shift issues and kr. I had 92 octane in the tank and she rattled on the last pass at the 1000' mark so I let out and blipped the throttle a couple times to a 13.54 @ 102.46. Last time I weighed the truck before the blower and hard tonneau it was 5880 with me so I'm pretty sure it's in the 6000-6100 range now.
Good weather is coming up and I'm working on the rev limiter/shift issues so we'll see.

Thanks guys!
BTW, I don't have a boost gauge on the truck but, had a 2 bar map on for the 3.4" and 3.2" pulleys. They were 5psi and 6.3psi respectively so going off of that I'm speculating that the 2.8" pulley is 9psi.
