Hello everyone i am new to the supra forum and this is also my first supra.. The car has factory injectors and does not have a fuel cut defenser. The car will only run smooth up to about 7psi, any more boost than that and the car stutters like it is starving for more fuel.:cry: I drilled out the aluminum cap on the maf and backed the screw out. This really didnt make much of a difference.. The vehicle has an aftermarket turbo(not sure what size),blowoff valve,adjustable fuel pressure regulator,hks performance ignition system, and a straight 3 inch exhaust all the way out the back. If someone could maybe help me i would appreciate it!!!!:1zhelp:

Look for a boost leak first. If you have a leak, the AFM will measure more air than is actually going into the car, and fuel cut will happen at a lower pressure.
