E85 Tune 2013 Scion FRS Questions

First question: In CA i think e85 is heavily subsidized. So its 4.69$ for premium and 2.79$ for e85 near San Diego. That means e85 costs 60% of premium. With out a tune, i ran e85 for about 100 miles and i got 22.8mpg vs 30mpg. that is only 70% of normal mpg. meaning im saving money. Such savings would make it more attractive for me to make the switch to e85.

Second: this one I can google so just rough answers are fine. How much more power do you get? it is noticeable? I already have cold air intake and headers and catback on it. and my issue now is not very much power above 3000rpm.

Third: it was hard for me to find someone to even do the turn here. Alot would not touch toyotas. He quoted me 800$ plus 200$ for a license (another 180$ if I wanted to maps to go in between e85 and premium). And then 150$ for a fuel pump which I was going to install myself. is there a cheaper option? I am willing to drive to Phoenix if its like 400$.



Thank you in advance for your help.
