I have the lund flex tune. You'll need the LU-47 injectors and his or AED flex tune. You'll have to datalog on reg 93-91 octane. Might revise it 2-3 times. Then get it close to empty. Fill with e85. About 10-15 mins of driving you will see a difference on your afr's. That's when your ecm has adjusted to the e85. Then send another wot datalog on e85 to see if an adjust needs to be made. With the flex fuel you can mix gas n corn with no issues. Mpg will drop though. The tune goes off your factory wideband. Adjust as it senses it. Your knock sensors will keep adding timing till it senses a knock and will adjust. It will make more power vs 93 octane.
