There is NO horsepower to be gained on a stock motor switching injector sizes. Use the size your ECM is programmed for and drive happily ever after.

Actually, I spoke with Bob at FIC via email. He was very helpful. FIC does ROCK
Got to be careful with that eBay stuff. I was able to connect with the seller (Doctor Injector, Inc.) who sold me the wrong injectors. They did agree to a return with full refund. But, they did try to tell me the LT4 had low impedance injectors. Proved with data they were wrong to get my 245.00 back.

No No... just order the 26# Bosch III LT4 Customs form FIC today. Those post were just ramblings of considerations.

However in discussions with Dr INJ they insist the low impedance are compatible in my 96 LT4 Corvette, although I personally haven’t found any evidence of that. (GM PN 17091654) If the 96 Corvette PCM is capable of running Low Impedance injectors, then that leaves the possibility that there is a bad injector on the INJ2 circuit that blows the fuse when hot and operating at full rpm. The injectors all test 2.3 ohms cold and at engine operating temp. Either way they are taking them back and will test them. The car runs fine when I replace the fuse, although scanning shows misfires.
That leaves me with this question on the forum. Does any one know if Low Impedance Injectors will operate on the 96 LT4 PCM without Modification. Just curious, will know more once I replace the injectors.

As I said Doctor Injector Shops, INC are taking the injectors back for a refund. I am pulling them out tomorrow. My Bosch III from Fuel Injector Connection are arriving tomorrow.

I am still following because I am curious of the last question as well. Not surprised it blew a fuse based of V=IR. If resistance goes down in a constant voltage circuit, the Amps must go up. If the circuitry isn't built for the amperage, it melts down. I do hope that since you blew fuses it did it's job and protected the circuitry from an over current condition.

BTW... the FIC Bosch III LT4 Cuntom 26# injectors perform perfectly.
