I don’t like black boxes. I know the Mustang’s limit is 145. You can feel the limiter kick in, otheriwse it would go a good bit faster. But, my year’s Mustang wasn’t built for top speed, it was made for the 1/8th and the 1/4 mile.
Of course, I could remove that with a Predator tune… but if I was to do that, I might as well start doing more things too.
As of now, it’s all stock, except the exhaust. I have SLP Loudmouths instead of the stock mufflers.
Oh, forgot to mention, I’m creeping up on 140,000 miles and still going strong.
