Ok, I changed the injectors to 42lbs in LT1_edit. Do I need to change the injector offsets also? I found an Excel calculator on someone's website, but I don't know if I can trust it. Should I just change the offsets by some percentage, and see how it runs. I've got a TE wideband if that's any help. The car is a 383, 9:1 CR, and a 60-1 hifi turbo. I'd like to get to idle properly first. It won't stay running as it is, without giving it throttle. All i've done so far is the injectors are set to 42lbs, and the cylinder size to correlate with 383ci. Any help would be appreciated.

 

Don't trust them, every car is a bit different. Just use your stock offsets and run and scan the car. Check your fuel trims and then make an offset correction if the BLMs are not in line.

 

Thanks. That's what I've decided to do. It shouldn't be all that hard to do.
