Got the 03 version of the ZX3 and best I've seen this summer is 36 mpg avg...now down to 34 or so. Mine is a California model and I'd guess the fuel mix is more controlled by the rear O2 in order to provide a complete burn in the cat...or so I've heard.

Also mine is an auto.

Will be testing the Volo chip soon.

Here is a pic of a new mod I just finished:

Made of 3/8" sheathing plywood...edges were painted with fiberglass resin and 2 coats of oil based paint put on. Made the mistake of not paying attention to warping...after the sheet is off the stack...they warp. If I had made it so that it warped DOWN...I wouldn't have needed the stiffeners. Drilled 2 holes in the xmember to hold it at back...2 more will be in the plastic lip at front...4 in all. The hole in the middle is for the cat and exhaust...they don't sit down in the hole...just there to keep the heat away from the wood.

I THINK this will be more effective than the lawn edging I had on the front...not to mention that it would never handle the snow. At the back it is at the same height as the lawn edging was. I figure a gradual redirection of the air is better than a blunt forcing of it to the sides.
