listen to @ nelsmar you need to get some logs of general driving to see what going on.
as nelsmar said AEM intake will require MAF rescale or you could get problems and CEL codes you describe was it installed after tune ? also leaky exhaust gaskets near either 02 sensor or engine can throw readings off and cause rich/lean issues did you use new gaskets when headers installed if you re-use the originals they tend to leak after about a month. ??
If you can't do propper logs (torque is a bit slow refresh rate and cannot log all the required parameters) take it back to tuner before it gets worse and more expensive.
If it was me I would not be going WOT with that cel code coming up. |
AEM Intake was installed before tune. Tune took intake into account. Brand new OEM Subarau gaskets were used for header and OP. I can take logs using ECUFlash software. What RPM ranges do you suggest I log?
