Finding decent gas here in Colorado is pretty difficult. Most of the 91 octane here causes knock (tuned) on the stock tune it does fine but tuned the fuel doesn’t hold up. Running an E50 tunemixing E85 and 91 results in a fantastic fuel for making power. Especially in the heat.
I do run an ethanol lubricant which does quiet down the HPFP noticeably. As for fuel consumption. Its higher as expected, my average mpg is 14-17 mpg depending on if I don’t burry the peddle at every light.
The fuel pump duty cycle and injector PSI do not drop from their commander values which indicates the fuel system is adequate for the higher fuel flow.
By no means do I imply people should run E50 tunes, that ethanol is “good” for your truck, or ethanol is safe long term. Just sharing my experience.
