Switching to E85 or 91 for better towing

Post by pacho »

I have 4x4 2007 Siverado 1500 Classic with flex-fuel 5.3l V8, 3.42 axle ratio, z71, z82, and 4L60 transmission. Considering that live in an eco-terrorist state, which is better for improving my towing capacity with T2 tuning, E85 or 91 octane gas :?:
