I just got another set of GasPods - hope to put them on today. Innteresting, my mileage was a bit (1/2 mpg) lower than I thought it should be the last 5-6 tanks, and I wondered if i was getting new winter gas.

I pulled off the wheel discs to check my air pressure, and found they were down to 35 psi, when I had put them at 50 last fall. I topped them off, so we'lll see what happpens now.

Have you considered doing a tuft test focusing on the trailing edge of the roof and side panel?

I have considered it - not sure that I'll get around to it.

I sent that same photo to the GasPods folks this afternoon, and they said that they'd like to see the side ones moved forward a foot or so, to allow the air streams to recombine a bit before the end of the car.

We decided I'd try it as-is for a couple thousand miles, then move the sides forward as they've recommmended for the nenxt data point.

Nice illustration of the difficulty of drawing conclusions about mods when other variables are changing. Tank-to-tank testing isn't ideal to say the least!

Absolutely! Here's where I am to this point, in a different format.

Just got in an internal sideview mirror - works really well. PVC conduit offsets plus a 1/2" MPT adapter; bolted through coin tray.
