Uncle! Supercharged 2018 Charger Lean at WOT

[SB2PRO]

I am reluctant to post this problem, because I know it will be something stupid, but here goes. The car was originally a 5.7 but has been stroked to 431 c.i. and now has a supercharger added. It has FIC 1200 injectors. The car goes lean when transitioning to WOT, and I haven't been able to make any adjustments to solve the problem. I have raised the VE table in the WOT regions and it did not respond. I raised it to silly levels and it still shows lean. It commands the PE early and even goes rich for a second, but quickly goes lean and I lift. I started with the FA inc rate at .0006 and worked up to a max of .5 with the same results. The injector pulsewidth stays around 6.6 and doesn't increase above that. At this point, the boost is very low ( 3 psi) and the fuel pressure shows good (maybe dropping 3 psi or so to 55 Psi). The injector duty cycle is very low. I feel like the computer is limiting any adjustments. Any help would be greatly appreciated. I have attached a sample log and tune file.

Thanks

Adjusted your PE Rate Try it. Let me know. Keep an eye on A/F

How did this turn out for you? I having similar issue with lean transition into wot. Causing knock. Tried the same steps to correct as you did with no help.

The solution provided by JnJSpdShop was the problem. I had changed everything for boost, but failed to update the Max Map limit. I went ahead and bumped the FA inc value up to .001 just to get the fueling to come in faster also. I had already maxed that out before and it wasn't the core problem. Good luck.
