I'm going to replace my fuel injectors on my stock 1989 Corvette. I am planning on going to 1.56 roller rockers. I think the car is stock 22 lb per hour. Is this the correct FI. I was thinking BOSCH 3.
I don't feel that the lift is enough to need a larger injector, correct?
Thank you all

Currently keep the injectors rate exactly the same.
Bosch III has a updated spray pattern. Better pintle technology.
No need jump up. Your originals have superceded the task. They can retire proud.

You can pay a service $200-300 for Bosch IIIs or find exactly what the flow rate and ohm range on your stock injectors are and do a Google search to find the same spec Bosch IIIs. I got a "rebuilt" set of 8 for my 92 for $40. They work great so far. The 96 Frods have the Bosch IIIs with the same specs as my 92. I also did the same thing on my 93 jeep years ago. The 96 Dodge Neons have the Bosch IIIs with the same flow rate as that. This is one of the best mods in my opinion. Smoother idle, better mpg and slightly more HP.

I went with Bosch III 22# for my 89. And found it ran lean via data logging and then swapped them out with Bosch III 24# from FIC which the data logging scans showed was more in range.

I do have the Tuner Pro RT. I will use it when the new injectors are in. Thank you

Call Jon at FIC. He sold me a new set of Delph's, car runs amazing.

I'm in Okinawa Japan. But, I did email him yesterday. I'm hoping to hear back from him. Delphi not Bosch III? Thank you
