Your product it sold nation wide.. and there is a need for Flexfuel tune.. or at least confirm if we can used with 91 tune.. I would be highly disapointed with the product if there is no update soon.. many of us are loyal to the brand... keep us poted.
To be honest, you will not see us having a tune for the fuel.
Hopefully we can confirm in the future.
If it were my truck and I was die hard about it, I would test the fuel with the tuning. You can use the advanced data acquisition to verify your results.
