Philip,
Don't even bother with the Volo chips. I forget what vehicle you're using, but a digital EFIE will be better.

Karma,

I am surprised you asked that question, since we've posted a lot of lessoned learned from the Volo including myself. Go with the EFIE, if you got one from Fuel Saver. start with 400mv and let the ECU get used to the new condition, then slowly decrease it. several clients are set at 400 mv front and and 20mv on the rear. In this setting it is forcing the ECU to go with the front signal vice relying on the rear, besides Ford is the only manufacturers that relies on the post cat O2.
Oh yeah, make sure you are producing the gas you need, and start with 1.3 of the eng displacement. I've been experimenting with "less is more", my 6.7 lkiter diesel yield better with 1.75LPM vice the 2 +lpm if I was doing the .5LPM per 1 liter of eng displacement.
