it does cost more, but keep in mind that it's 105 octane.

Ok great but if you do not have a reason for the higher octane what is the point? The average driver dosent use any forced induction or a compression level high enough it would be needed.

run more timing to take advantage of it. when the truck is in flex fuel mode it puts down over 300 stock.

If you mod great it will work perfect but for stock, i personally do not think it is that great of an idea.
