OK so the mustang is what it is. I guess there’s no tune on it but what happened to the spout chip? It’s a remanufactured CPU unit, did they alter it when it was being re-manufactured? What do you suggest?So two different worlds man. On the EEC-IV the only way you get multiple tunes is if the chip is like an SCT switch chip (I have this) and has a cable that goes to the chip that allows you to toggle between tunes or if you have a Quarterhorse or similar tuner and upload different tunes to the chip.
With your truck you actually write to the the processor and change the factory programming and there is no physical aftermarket chip. I will also say that your bad gas mileage with your truck was directly related to your foot. My truck is tuned and the mileage sucked at first because I was driving it harder than normal because it was fun. Got used to it and now drive it normal with the occasional rip and it does fine.
It was a Banks programmer I tried on the truck and had to run premium fuel. Sent it back and put a cold air intake with a TB spacer. Plenty of hp (about 415) with 20 mpg at 70. Love my Coyote 10 speed.
I’ll put everything back on the stang and try to set it again.
