So the night didn't go as planned. I expected to come home with slips in the 11's Everyone was complaining about bad trac prep and poor traction.
I'm sure my issue was a combination of track prep and my lack of experience. I could not hook up to save my life. Started off at 20psi and ended up at 16psi, didn't seem to matter at all. I had better 60' times when it was stock and on runcraps. ??
I am low tech and can't seem to get the slip images to show up, so her it is.
RT- .350
60'- 2.196
330- 5.614
1/8- 8.309
mph- 92.06
1000- 10.625
1/4- 12.577
mph- 115.64
I ran 4 passes and they were all about the same. I tried to launch from 0 rpm, 1000, 2000 and 3000 rpm's and it didn't change.
I was doing the same ET as a guy with a 2013 427. He should have been faster than me me. He could not hook up either.
Time for some sticky mickey's with a higher aspect ratio I think.

Now, not that PSI doesn't matter, I just mean for example, if it is over inflated then definitely drop down but if it is street inflated, then you should only raise or lower within a couple PSI. Each tire is different. Each tire has a different happy point.
On my R2 tires I got 1.74 60' on 23 PSI and 2.0s on 18 and 19 PSI and that is an R compound tire. Additionally, my tire got better traction on a 3 to 4 second burn out than a smokey one. Contrary to popular belief, not every tire enjoys the same levels of heat as the next.
Basically, a tire specific combination of heat and psi is needed on an R compound tire. On your NT05 (which I assume isn't an R), burn outs (if you did one) will not help.
People will argue this all day but street tires do not do well when burned out or big drops in PSI.
Most of those people who swear by it are people who went from a 2.2 60' to a 2.1 or 2.0 60'. Those are all bad.
On 275/40/18 Nitto 555 NON R street tires I nailed 1.81 60' times repeatedly in my 06 Manual Mustang on 4.10 gears that made 340 WHP and 320 lb/ft of torque by launching at 5500 RPM on 35 PSI with NO burnout.
Street tires and lower end drag radials do not enjoy shock. So clutch dumping or Stall "dumping" really kill the 60'. Now tires like ET streets which are barely a street tire, are fantastic with shock.
On my 305/35/18 Nitto 555 R2 Road race tire (R compound drag basically with a side wall), I was able to bog my way to a 1.74 launching at 4500 RPM at 371 WHP and 332 lb/ft

A low 1.9 60' will get you an 11.90 easy. On street tires skipping the burnout and NOT dropping PSI is better.
