Help! Launching at 5000k RPM on ET Streets and it BOGS?@#$

I have the stuff in my combo, plus 26x8 ET Streets. this is the first time taking it to the strip with my new stuff, and i run an embarassing 9.24@77 on my ET Streets. The weather was about 70 degrees and 45% humidity.. great racing weather. I went two weeks before on my regular radials, and run a 9.02@81 in 80 degree heat with 70% humidity!@#$ I had to launch at 4 grand on radials to even get the tires to spin a little (if they dont spin, it bogs BAD.) Why does my car bog when I launch at 5k rpm on slicks? Are the Track Heat intake and the 70mm TB THAT big? Too much for my other stuff? I'm running 35psi fuel pressure with stock pump, and 16 degrees timing. Not enough fuel PSI? I couldn't make any other runs because the track was so crowded, but DAYUM. I got a better 60' time with the radials! Help!
