We run the same car. I looked at your slip and seen that nice trap time and low trap speed. What are you launching at? Your trap speeds are way low for sure, but so is your boost that you could be running. Yea it's hot out, but compensate that by spraying the intercoolers with ice water before each run.
You have the traction down I see by those nice 60ft times and to still land that low of a time with that trap speed. But somewhere along the way your car is loosing mid to top end. I have my timeslip of just a few months ago where I ran my car with NO 2nd gear at all. So drop a full load of boost going from 1st to 3rd ( tranny 2 is gone ), and ran an amazing 16sec time at 109mph. I posted it here the day after. The time of 16 came from me trying my damnist to get in gear. But as you can see you should be running better times to. This was an autocross track to, that they use the front straight away for fun night out 1/4 mile racing. So not prepped or anything. But I was running 18psi on race gas. Not sure what your using for gas or tires.
But the car also ran a 13.1 at 110 on 15psi and 105 gas with my 18" rims ( weight 210lbs w/tires ) too. And it was 90+ that day too. You might be shifting to late and dragging out the cars power band and losing top in that way. Not sure yet bro........
