My 03 gt needs more fuel. I had it on the dyno at mustang week and it's a/f ratio was 14:1. My programmer is maxed out on the amount of fuel goin to the motor. Is there a was to download load tunes or mail order or something that cheaper than dyno tuning for right now. And also how do you use them. FYI I have an sct programmer. I will eventually get it dyno tuned when I have more money b/c I know its ultimately the best for the car.
