This past weekend I went on a road trip with the Cobalt and my plan was while on the drive, I was going to maximize the mileage! So I played and gained a SUBSTANTIAL amount of MPG's! Im now getting better MPG on the E Blend then I was getting on 93 alone. Given, if I work on similar changes with the pump gas tune I could prolly make that better still. This was till a huge improvement!
Here's my Cam and Timing Tables:
All of the Cam and Timing tables match those, meaning all of each are the same as teh 1 posted above
See if you gain some MPG's as well!
