That heat is killing your times. Next time you are at the track, get a couple bags of ice....and put one on you IC pipe going into the TB and one on your intake manifold. Let it sit for a good 30min.-45min. and then have some friends push your car to you get to the front. Start her up and rip down the track. I am POSITIVE you will see at LEAST .2 gain and 2mph.....trust me Dave and I do it everytime....and it works.
