Upgrading injectors, What do I need? Options

[joeladam02]

I have a set of 315cc injectors from a 7MGE Supra.
When I tried them in the 5sfe the car dies at about 4500-4700 rpms in every gear, with the pedal to the rug.
My question is, should this be happening going from the stock 220cc injectors?
Will the computer automatically adjust the fuel output over time?
Or do I need something else to tell it how to regulate the air/fuel ratio?

Nope, runs up to 4600-4800 RPM's until the ECU starts trying to lean it out.

But the injectors were really just used for test purposes anyways. Had an engine misfire, and was going to use those injectors to rule out a problem with the original injectors, but it just compounded the issue really.
I think they're out of an older Supra. 315cc light green ones. The only reason I even have them is because some guy named StephenAudet on here sold them to me as 5sfe injectors, when they were really like 4AGZE injectors or something...
