Doesn't it depend on each individual car? Like doesnt it vary from supra to supra a tiny bit?

Yes, it varies by car, temperature, humidity, how hot the car is, how dirty your intercooler is, etc. But at 11 psi, if its pretty warm (>80) pretty good chance that youll hit fuel cut.

Reeves...I'm going the other way. Did the suspension first, will go for more power next so I'll trade ideas and experience.

I just installed TEIN Flex coilovers. Had the car on track after TEIN last week. HUGE improvement in body roll and handling. These TEIN are very adjustable so you can really dial in your set-up. (I will be putting on proper rubber before next track day, probably Toyo RA1's but open to suggestions)

If you get the TEIN let me know before you install and I'll share a few tips.

Also...while I was on track my car got very very hot after about 6 to 8 hot laps. (it was about 95 out) I have a recent new head gasket so I don't expect leaks there. Any suggestions anyone?

this car looks really good!

i think your car heating up is normal in the hot 95d weather.

All cars are different. Fuel cut occurs at different points, at different times.

I had a religious fuel cut at 15psi exactly.
I tuned my ProfecB specII to hold a rock solid 14.7psi and it never hit fuel cut.
