The vvti 1jz engines don't necessarily hit fuel cut under the conditions you are describing but they do have issues with the spark blowing out. Look on supra forums to see info about high boost misfires. My car did the same thing for a little while until I replaces the plug wires and coilpacks. Also of you still have the factory diverter valve in place they leak at anything over 12 psi and make tuning a pain as well as cause other problems. I have been running a vvti 1j with the Tomei arms setup on 20 lbs for over 5 years now without any real problems. Big thing that helped was going to a power fc djetro and getting rid of the maf
