    E85 tune question,

    When getting a E85 tune do I need to upgrade fuel pump? Or do I need to modify anything? I currently run a 93 tune from ZFG, and get 16 mpg city driving at 4.86$ a gal. And we sell E85 at 2.86$ a gal. Is E85 worth it? Any info would really appreciate it.

    18o t stat. Good or bad?

    I installed a 180 thermostat. And had a tune adjust for the engine temp range . Only for the tuner to tell me it’s not negative with eco Eng bad for the plugs and bad fuel economy. Can anyone elaborate with this?
