I can't give away all my secrets but here goes in a nutshell.
The stock 02's handle the change in fuel, i simply allow a greater range of adjustment so it won't throw a check engine light.
The computer will automatically add pulsewidth no external boxes.
Timing is set-up the same as a premium unleaded tune so you won't lose as much economy.
The add-on boxes for fuel upping don't adjust the timing and you will lose close to 30% economy on e85 that drops to only about a 15-20% loss with my tuning.
You get the program on a custom programmer similar to the brand X you can buy and re-flash your truck...
You can put gas in the tank and it will drive normal without having to reflash.....
Also vast improvements in drivability on gasoline through my tuning of the transmission and other items....
