EGR Valve?

Anyone tried to block the EGR Valve closed? I have read in many places that this would be beneficial, power wise. Opinions? Also, where is ours?

Newer toyota's do not have EGR valves. They use the vvt-i to tune the car so it does not need one. This is also a good reason not to mess with the vvt-i setting unless you really know what you are doing.

I'd be surprised if there wasn't one. vvt-i timing adjustments or not, it can't handle things like cold-start conditions and whatnot.

actually EGR is used to cool down cylinder temps and wouldnt be beneficial to remove anyways. id suggest leaving it alone

EGR recirculates burned gases back to the cylinder, just like a PCV hose. It's for emmisions.

understood it is used to ensure that unburned fuel is recirculated to be burnt, but it does cool down cylinder temps and you will gain litte if any power at the loss of emissions and mileage
