already looked into it... and sadly the answer is no.
the mr2 and alltrac use the map sensor reading to put in fuel cut when a certain level of boost (manifold pressure) is reached.
on the supra, the computer is programmed to shut off fuel when a certain frequency is reported from the afm. which means, that it is limited by certain amounts of air at each rpm. ex. 500cfm at 4000 rpm. the computer has various points to refer to, and if the airflow exceeds the max at any given rpm, you get fuel cut.
the only way to bypass it is to make the afm think it is seeing less air, and tune with something else. a la lexus afm and 550cc injectors, safc, a maft setup, or even the good ol vpc.
the hks fcd works too, but it it just a circuit that is programmed to interpret the maf signal and output the maximum allowed airflow at all rpms. it never lets the computer see that the airflow has exceeded the maximum. imho, its too expensive for just that.
