Default bogging at 2000

ok i have been tuning my own car for a year now no problems. i put a mild cam on top of all the bolt ons i have. the car has 85mm tb and intake manifold with long tubes off road y pipe loud mouth 1 2800 stall and 3:73. i tuned it and the car runs great idles right at 850 no problems has tons of power but when i took it to the track on wendsday the car would bogg at 2000 rpm when i would try to get up on the converter then would "drive" out of the whole. im thinking its running to lean at low rpms to come up on the convert. any ideas?

if it was the o2s wouldnt it run lean through out the rpm range? cuz it runs strong as soon as it gets above 2500 rpm. wendsday the car went 12.9 with a 2.08 60' there were no problems with the o2s before i did the cam swap

I dunno man, if you have a tuner it should be throwing a code if it was the o2's so if its not im not sure what the problem would be.
