Still 10.0 afr with aem tru boost and wideband!
So I have pretty stock evo 8 with basic Boltons exhaust, piping , etc. it has stock injectors still with a rewired walbro 255. The aem wide still reads 10.0 afr at 18-25 lbs at full throttle? I don't get it. I also have a aem tru boost controller and the wastegate crack is set at 11.0, should lower the crack setting?

Has your car been tuned?

On my TRU-Boost i have SPR at 7.3, Setting A at 58
also reading 10.8 but the car is untuned. A tune will take care of the richness.

With those modifications, you should really get a tune. I am sure it will fix all your problems. You can't install performance parts without a tune on turbocharged cars. Good luck.
