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?

 

No not yet!

 

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.

I love these threads where people put parts on and are like, wtf why is this happening. Do some research for gosh sake.

 

get it tuned so it will run properly and fix your afr issues. Evo's run very rich to begin with from the factory.

 

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.

 

you just need a tune buddy
