88 Supra
 

Hey guys, I just put a new engine in my 88 supra, it runs amasing, but the only problem is it cuts off when I try to floor it, the turbo will work if I slowly give it gas, but if I floor it, it will jerk and cut off, the computer is fine and never been played with..any opinions ??

Is it completely stock?

Yes the car is completely stock, the new engine came from japan. I took it to a performance to see what the problem is, they say it might have something to do with fuel or fuel pump
