Anyone else having problems with driving in the summer

Mine ran great on Sonoco 93 no ethanol, a while back they had to start putting up to 10% ethanol now I can't get it to run good no matter what I do! I have an MSD fuel injection setup on the shelve I guess its time to get off my lazy *** (bad back) and install it. After all most of you fuel injection guys say your cars run so much better and you would never turn back.
