Blanking the EGR in 2015.





A few months ago, I made the decision to remove the blanks in my Innova 2.5 D4D and restore the EGR functionality. Power delivery immediately became smoother with the EGR valve working as it should.

Back when the EGR was blanked, power transition was rough and edgy... for lack of a better word. It gave the perception that the engine is more responsive. I attribute that likely to a more potent fuel/air mixture.

But there's also the guilt associated with giving off excessive NOx emissions. Mistakes were made but that's in the past. Though, I would have to suck it up (no pun intended) to have the whole intake de-carbonized in a few years. Hopefully, I would've sold the car before then.
