Absolutely.
Could you elaborate? I have a 2007 Tundra with that is in limited power mode due to SAI codes. I have unchecked all of the SAI codes which keeps the check engine light out, but it is still in limited power mode. I am not sure what I am missing.
Changed values under (airflow-electronic throttle-sec air-fault a-fault b). No more limited throttle.
Does anyone know if the sai valves need to be blocked off? And if the check engine light comes on or can be disabled?
Thanks
Perfect thanks! I assume that the valves under the intake are what should be blocked off? Anything else?
What are these SAI system your talking about?
Truck has supercharger on it, I assume need to raise TPS to 86 or so so its not torque limiting?

"secondary air injection" it seems to be like the old '70's air pumps designed to scam the emissions testing equipment
What did you change the values to?
For no throttle intervention due to SAI fault, increase the values in the Engine -> Airflow -> Electronic Throttle -> Limits -> Sec Air Fault -> Air Fault A/B tables to a value equal to or greater than the values in Engine -> Airflow -> Electronic Throttle -> Max Rotation -> Max Angle/Max Angle B (86 degrees in a stock file).
Thanks, slow stock! That's what I figured, but wanted to double check. Hopefully this will help the next guy who does a search.
So did this work .
