Hey Guys,
I've got an 86 Trans Am with a 350, TPI, 700R4, and a 2.43 posi. I am in the process of putting it back together and have never actually driven it so I have no first hand experience with actual gas mileage for this combo. http://www.fueleconomy.gov/ says the car was rated for 17-25 mpg in stock form with a 305. I am thinking about a mild performance cam, and an adjustable pressure regulator as the car was originally a 305. I would imagine that it would run fine with the stock computer and chip but that seems so boring. I'd love to find an excuse to play around with a megasquirt setup.
Here's the questions:
If I tune for mileage how far can I push this combo if performace is secondary? (If I could get a consistent 25-28mpg on my 80 mile per day commute I could drive this in the summer and not my 95 Ford Aspire.)
If I tune for mileage, do I have to stay out of the gas all the time or is the mega squirt flexible enough to run a mileage tune at anything under half throttle and something more fun over half throttle?
Any help is appreciated.
