C38, 93, injector/pump upgrade or no?
 

First - apologies if this has been answered and I haven't seen a definitive answer. Have a Kraftwerks C38 kit and prepping for install, for now going to run just 93 octane exclusively. I've read around the forum and found:

- most say you don't need injectors for standard pulley on the C38 with 93 octane.

- everyone says you must upgrade pump and injectors for E85

- everyone says you must upgrade pump and injectors for HBP

But what I'm a little unclear on is - while not absolutely necessary, are there any performance/safety gains by using larger injectors/pump with 93 octane fuel with a Rotrex C38 kit? I've read some things alluding toward the fact that it *might* be, and I've read some things saying there aren't any benefits. Nothing definitive.

Thanks!

Never mind, finally found the info needed

No need.

If you're on pump then you should be fine with stock fueling. If you do the HBP and the c38, then it would be good to get injectors at the very least. But with that said, we strongly advise against running the high boost pulley with a c38 on pump gas. That is 15+ PSI above 7000 RPM, which is not exactly ideal.
