would it be bad for my car if i tuned for the first time along with a boost pill and e85. im just wondering if you should do the e85 after or if it doesnt matter

 

From what I know you'd want it tuned After the swap over to e85, because you have to tune for the fuel you'll be running. There is a bit to doing the e85 swap though... injectors, possibly a different fuel pump and I believe other things. Like I said "from what I know". Ask a professional tuner to be sure though.
