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.

stock fuel system can easily feed your bolt on GT. You either have dirty injectors or the fuel filter is very clogged or its your tune its crap.

filter can get clogged very fast like 10k miles. The injectors could be dirty also with that mileage. step one fuel filter and see how it goes if its never been changed then its a good chance thats the problem.
