Yeah that would do it. On my X the ports on the bottom of the DPFE sensor are different sizes and so are they on the EGR exhaust tube so it would be hard to confuse them.

I recieved the XCalibrator today and reprogrammed my PCM to the 87 performance setting...OMG THIS THING IS AWESOME!!! I noticed a little difference on normal city driving BUT I took her on the freeway earlier and OMG dude she just took off! I have NEVER accelerated to 80MPH that easy before! It's like my truck has been reborn! THANK YOU! It also seems to have took care of my EGR rough idle issues and my CEL for the rear O2 just like Doug said it would.
