It's supposed to be 1-2 mpg more but I didn't see it.

I didn't see it either from the efans.

I didn't see any benefit after installing E3 spark plugs, and removed them after getting some misfires.

I never used them either.  I used Iridium plugs by Denso. $13ea

I can't recall but i think i use either NGK Iridium IX or SplitFire Triple Platinum    lol...i dont remember

I was wondering if anyone has used a Hyper tech programmer or Fitch fuel catalyst running E85 fuel and what the MPG increase was? I am trying to install the one that will make the best improvement first then maybe the other later. Right now I am getting around 13.4 MPG using E85 in my 05 FFV avalanche. I have already installed a K&N air intake and would like to go further using less fuel.
Would appreciate your input on this, Ken.

Spark plugs next. I dont know much about e85 as my truck isnt compatible.   Before you try the Fitch Fuel Catalyst,ask the vendor if its compatible to e85 engines. I looked at their FAQ's and no e85 info was available.
