Is it possible to change to a 2 or 3 bar map sensor when using the AFC hack to increase boost pressure above 10 psi without throwing a CEL? Is there anything you can do to go above the 10 psi while using the AFC hack?

 

You can scale back further than flow differential, and increase fuel pressure. Though that is NOT advised.

Don't be cheap on Engine Management. If you want to run high boost (10psi +), do it right. Get ECU tuning.

 

the tuner told me that anything above 10psi+ he wouldn't trust the safc.

 

i tried to make the 3bar work using just the afc and that plan sucked *****. just chip your ecu.
