    Sorry I’m a new gen 3 owner and I’m curious why there hasn’t been a mod (besides emission compliance) to chop the pipe coming from the exhaust to to the egr, cap the exhaust to egr cut part and the route another pipe connect it to the EGR. Either plumb it into the bottom of the air box below the filter or somewhere else using another filter to draw in fresh air rather than exhaust gas.

    And what do you think's going to happen when you do that let's just go with that first?. What do you think the car computer and systems are going to think about that? I'm not trying to be smart I'm interested in knowing what you might think about that We used to do mods like this over on the Toyota modification server years ago The guys in Australia and New Zealand are experts at this stuff not on a Prius mind you but I'm thinking that that's not going to work on the flood EGR type system that is on the Prius somehow the Prius uses that EGR as much as it uses fuel from the gas tank practically that thing runs the two Z runs on its own puke like a bird feeds it's young it's disgusting but hey that's what you got to do to get 5% more gas mileage over the generation too or whatever and that just gets fouled up clogged up and turns into a jigga mess.

    That would certainly change things!

    The EGR system uses exhaust gas because it will not chemically combine with fuel the way fresh air will, so it can be used for dilution without leaning the mixture.

    Fresh air would have ... different ... effects.
