You sure it's got enough fuel in the MAF/VE?
You also didn't change the cylinder volume, so it still thinks it's a 4.8 engine size.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
ohh yes thats true l need to make that change, ill make that change soon any other change i should make for the e85
seems to run but as soon as i let of throttle turns off.
Just like 5F said, adjust for the proper engine displacement, then you need to change the Stoich AFR to 9.8.
After that, open the throttle blade to allow additional airflow into the engine. You didn't say what TB you are running.
If it's a stock TB, you can open it up until your TPS is between 0.80- 0.82V. That'll be a great starting point.
I assumed he set the stoich to 10.50 because it's just pump E85 that is more like E70ish at a gas station.
