Default 08 C6 E85 Conversion

I reached out to the people who tuned my Vette and asked about switching to E85. To my understanding, I wouldn't need to replace the fuel pump or the injectors all I would need to do is buy the fuel sensor kit and get a retune. The problem is I can't really find any solid information to back what information i do have. When I asked him about it he quoted me at $3k saying that would cover tune, labor and a new fuel pump. Before i even responded, because im not sure if he even remembers that he already worked on my car before, I wanted insight on what exactly would be needed to do the conversion and roughly what the price should be around to do it.

I have a base C6, auto, K&N intake with cat delete and borla atak cat back system and it's currently tuned on 91.

So all I really want to do (for now) is get it retuned for E85 using the DSX flex fuel kit.

I run e85 on my 08 as well.

I put larger injectors in (flex fuel truck injectors) and the sensor - thats it.

I would not run stock injectors. The duty cycle will be insane.
