Are there any advanced tune options that would safely improve performance over the quick tunes? I am running the 87 octane on a stock '08 F150 5.4L. I raised the speed limiter but the only options are "raised" or "stock". My tires have a speed rating of 112mph but I have no idea what the stock limiter is set at. I also raised the rev limiter (which also only has "raised" and "stock" options) but it doesn't feel as smooth. Is it safe to raise the speed limiter while keeping the rev limiter stock? Or would using the quick tune provide the best overall performance?

Thanks.

Our quick tune on our Ford products has everything MAXED on the shift patterns, with raised rev and speed limiters.
So I would say that the Quick is the most performance that the tuner will offer.

You can raise the speed limiter without the rev limiter being raised.
