I have an abundance of 36# injectors laying around from my GTP days and would like to install them on my LS1. Problem is they are 41# on LS1 fuel pressure as I am told by SSmokin (verified by me) and I don’t know how to do the simple task of scaling the flow rates for the PCM. I would like to learn how and not just have a table thrown at me but I will take any help I can get. Thank you for your time and expert advice.

The concept of larger injectors on a stock car is for E85 considering 93 octane is gonna be over $4.00 next week!

I think the simple fix here is to buy another GTP to put them on

That’s a little helpful. I couldn’t find that when I searched.

As much as I would love to I am not currently in a financial position to make that decision. LOL
