A lean afr must be fine since youre running factory timing? Unless u have an egt gauge u should really keep the afr ~11
U put on a turbo that's way bigger and youre running way more boost than stock, you need to change the load columns and the timing
Zeroing the delays is just gonna make your gas mileage worse.
Don't analize about the pid loop. Just cut the factory turbo dynamics values in half. For the max wgdc just run a flat map of whatever makes u hit 20psi. So if it takes 70% to hit 20psi just make the whole
Max map 70, then make the initial map 60 flat. Done.
