Time slip questions?

[JTMunk]

My first time out at the track and my car didn't seem to pull at all in 3rd gear (C4 trans). I'm wondering if anyone can tell if I have problems from looking at my timeslip information. 1st and 2nd pull hard to the shift point (6200 RPM) but when I shift to 3rd the tack stays at 5000 RPM and doesn't budge. 3rd gear feels like I'm on cruise control.

60ft - 1.700
660ft - 7.760, 87.55mph
1320ft - 12.460, 99.56mph

Specs:
347 cubic inch, Twisted Wedge Heads, Holley Systemax intake, Trick Flow Stage 2 cam (545 in 565 ex), 42 lb injectors, 70mm Throttle Body, 80mm Pro-M mass air, Cartech fuel system with -8 feed -6 return, Paxton Regulator @ 45psi, PMS, C4 Trans, PI 3500 stall converter, 3.73 gear, 28 x 12.5 ET Streets, car wt 3200 lbs

Thanks for your help.
