Going Thursday for a dyno tune on e85 with full bolt ons. 6.2 a8 4x4 stock wheels and tires. Any guesses on numbers? I'm in south Louisiana and it will be probably 95+ degrees.

As long as the factory driveshaft doesnt grenade on the dyno, over 400 I bet.

Hopefully not. I'm guessing 410 being its hot as hell in south Louisiana this time of year. If it were January I'd guess 430

380...interested to see the results though. Will you have a graph showing RPM on the x-axis?

I should. Not sure what system he uses.

Made 415 in 4th gear. Not sure how to calculate what it would make in 6th which is 1:1 ratio. 98 degrees in the shop.

The easiest way is to order the kit from cjtunes.com then have your tuner activate the timing/fuel maps that already exist in the ecu. The other way would be go to a dealer and find a 5.3 flex fuel truck in the exact same body style as yours, get the vin from it then get the parts department to order all of the fuel lines that are different between the two and get your tuner to activate. The installation on the cjtunes.com kit is really easy minus the frame coating getting all over you haha.

I guess I should also add that mine averages 15.5-16 mpg with cruise between 75-80. Towing a 18' gatortrax mud boat it averages 10mpg cruise set on 75. I haven't pulled my camper yet on e85 to give a number but the all around power is awesome.
