N/A e85 timing add
I'm seeing reports of people picking up 20-30 whp on e85 on N/A motors with these 5th gen motors. I put a flex fuel sensor in and I'm teaching myself some tuning. What kind of timing is being added on e85?

My C7 with just a Dsx FF sensor with a good tune picked up about 34 rwhp, its been a couple years now but it was right in that area. As we were doing a few more bolt on parts we continued to make more power. I think we finally made about 465/471 with Ported Msd and Lt5 TB, long tubes and x-pipe. So we picked up a total of about 65 rwhp with bolt the on parts I listed. I never look at the dyno sheets I look at the ets from when it was stock. Ran 12.05@117 in stock trim and 10.90@128 after the mods and a lot of tuning. We were at about 28 degrees of timing on E65 and shifting at 6700 rpms with not internal mods whatsoever. With drag pack it weighed 3272 with driver and I weigh 200 lbs. Lost 45 lbs going with headers and expipe and almost 75 lbs with drag pack over the stock 18s and 19s.
