While this is nice and all, we have other factors to add in.
1. Are you a 2014 (different base map tune on 14's for one)? Which we all know to be a better tune.
2. What elevation are you at in Ohio?
3. Temp/Baro Pressure?
4. How much lighter are the wheels over stock? You dropped to 17's I see.
5. What size tire difference are you running now? Specifically height.
Lots of things can contribute to being faster at the track, I did it for almost 15 years til I had children. I still will, once I can get a break from work lol! First and foremost though, removing all that weight he did, might've gotten him 2/10's a second. It's ROUGHLY 1 tenth for every 100 lbs.. this has been known to fluctuate, especially in lighter cars so he could be gaining closer to 3 or 4 tenths as I don't know how heavy the seats are (front and back). Lastly, the biggest thing that will make for a good time is driver mod, it's the most important one. Lot's of time on the track accounts for knowing things to do, like when to shift, how to launch, feeling which way the car reacts to better, reading time slips and picking up where you need to, etc. I had a bone stock rebuilt 302 in my 85 GT and I took it to the track omw back into town and pulled a 14.2 and bout shit my pants. Soo.. that lead to only one thing, 15 years worth of playing with the Stang and drag racing/autox'ing it with my dad til one day she decided to butt kiss a F150. :\
Good on you for your run Nova, hope to see some more posted and some more great runs!
