I have been told my setup will be good to around 640 wheel with the 7psi pulley before running out of fuel? I've also been told I might want to consider a 4.13" pulley to go with 5psi to be able to run full e85? I'm not so much about chasing the numbers as I am to being able to run e85. PC techs have told me I will be fine with my 7psi setup on e85. I am sure there are plenty of guys on here with results. I haven't installed the PC on the car yet just trying to make sure I have everything sorted out. The current mods I have now are Flex fuel, MSD IM, 103 tb,2" ARH system. Thanks guys!!

You can either run the bigger pulley 5lbs on e85 or you can blend e85 and 93 and run the smaller 3.9 pulley. It is your call.
