How much HP from headers and dyno tune?

[bluestar]

So I just had my Pypes long tubes and high flow cats installed. Had my tuner put my Mustang on the dyno. It made 442 RWHP. How much do you guy's think I would pick up with a proper dyno tune? Car is a 2018 auto with mods listed in sig. Thanks!

The fitment of the Pypes Headers are great??

I could see another 15 maybe. But if you're doing a real tune go e85 if its available in your area and double that number easily.

The shop I had install them didn't mention any fitment issues at all.

Yeah, that's what some of my buddies were mentioning. I have to do a little more research on E85 as I really don't know too much about it....

Able to add more timing meaning more power. Engine also runs cooler. Safer, knock resistant etc. Many benefits. Mpg is really the only con, and possibly availability depending on your area.

Sounds like a pretty good synopsis!
