Nice power. Stock trans? Do you know the actual percentage of ethanol in your E85? Was this tuning done on the first tank of E85 that typically has 1-2 gallons of pump gas mixed with it? Someone asked what your IDC was at peak power, but I didn't see it posted. Could you post that?
Yes, I am still on the stock transmission at 108,000 miles. I did what I could to address the drivetrain aspect of the build while not having to worry about replacing the transmission. I do not launch the car at all and when I go to the track, I usually baby it off the line.
For the E85, yes, the is with the 91-octane still in the tank and the very first pull. I have since gone through nearly an entire full tank so there should be nearly all E85 in there at the moment. I plan to do another log here in the near future and send to Tom for his review. And for the IDCs, Tom will have to weigh in on this as I am not sure. I do know that AFRs were 11.7 in the upper RPM range.
Could be putting that 255 to its limit but looks like a fun build.
*disregard. I see plans for a 400. Does anyone ever think of the out of tank pump options out there?

Right now, my idle is set about 1,050 RPM. It has a very nice rumble and sounds like a small truck. Lovely. 
Yes, the 400lph is in the works as I know it will give me more headroom. I do my best to do all things with safety in mind.

I think its the ethanol content. First tank of E85 means mixing 1-2 gallons of gasoline with E85 and gives something closer to E60. Requires less fuel and still has roughly the same performance potential as E85.

Valid point. Well he's got safety in mind with a larger capacity line system and pump in the future. Would def keep an eye on things when running a full tank of e85 though.

Safety, first and foremost, my friend. Like I said, I will send another log to Tom probably Sunday evening to see if any tweaks need to be made since there will be more pure E85 in the tank instead of the diluted mixture of 91-octane and E85.

Strange as Tom did not mention anything out of order when he veriified the same thing for me. I am not saying that I do not believe you, my friend. I am just trying to see what the tolerances are for my set up in comparison to others.
