Default Is it a Fuel problem, heat or plugs

I need some help here. I went to the track yesterday. Temp was 89. Last week I changed the plugs. Put TR-6's in. When i lauch the car, it runs good through 1st, 2nd & 3rd. When I go to 4th, it seems like the car is running out of gas coming to the traps and through the traps. I'm just hitting the shift light coming on at 6800 rmp. You could just feel there was nothing there, like it was boiling the gas or not getting enough gas. When hitting the shift light in 1st, 2nd and third it felt fine, but then after hitting fourth and heading toward the traps, it really strained. Could that be the plugs? I am still running stock injectors. Could it be injectors? Best run today was 12.26 at 115. Most of the day was like 12.49-12.61 at like 113. Can anybody give me any ideas as to what this could be?

Is there a reason that one can ask "what do you think I'll run here" but I actually have a problem here and cant' get one response.

My guess would be you're not getting enough fuel. You really need a wide band.

In case anybody cares or wants to know, it was the heat. I went back to Lapeer last sunday and the car ran flawlessly. Ran 1st 11. 11.82. No problems at the top end at all.
