Default Help with KR (HPT)

Im tuning my car on my own, and so far so good. i made 3 passes at the track the first 2 where on the spot, but on my last pass i had alot of knock and i dont know how and or why? i changed nothing from the first two runs.

Did dyno the day before and all read well, put down 503 rwhp and 579 rwtq

and also in 3rd gear at the top of the track the car seemed to like being going in and out, like the nitrous was being turned off and on? i lost all power then it came back and so on. i have no idea what would make that happen..


mods are:
Cam, intake, full exaust, 150 shot (wet) no window switch, 4.10s/4000 stall,built 4L60E, ET streets 27x10.5x15

the 2nd run in the vid is the one with knock
