255 in fuel table
I have 2 spots in boost (140-150kPa @5500-6000RPM) where the values are at 255 and AFR at 13.2 while target is 11.7 for these cells.
What's the best way to solve this situation ? Everything else is on par with AFR target, only those 2 cells.
2000 LS, turbo Begi gt2560, stock injectors, stock fuel pump and fuel pressure, 13.2 req fuel in tunerstudio.

Um is the issue not stock injectors at 7psi?
Are you sure it's not just you're at 100% Injector DC and Autotune, or whatever is desperately trying to add more fuel to hit your target, but nothing's changing as you're already at max?
Req_fuel is correct for stock injectors...

I'm sure it won't be popular around here, but if you want to cheap out for the time being a $70 walbro 255 will supply more fuel than the stock pump. Should be enough to get you by for the time being I would think. Then again, some $100 RX8 injectors would give you a good bit more headroom.

Read the above posts: You're running stock injectors. They're too small for anything above 3-5psi or so. That's why you're running out of fuel. You can buy all kinds of other things, but the problem is injectors.
Buying a bigger pump won't help- only increasing the fuel pressure would help. And that's a band-aid at best. In order to increase FP you need an FPR. But get injectors instead and be done.

Idle is rough but i was only able to change the req fuel to 3.4 because the laptop died.
Going back atm.
Edit: injector 2 don t fire, 12V on white blue but where the hell does the purple / Green wireconnect?
Edit 2; wire going to 4x and to sequential injection board. Seems like thé board is defective. Will try to put it in batch mode.
