Plus if someone was butt dyno isn't that what's important? The driver? For me what's important is the driving experience and not numbers. I am not Richard Petty and all my driving is stop light to stop light, so feel for me is 100 percent more important than a dyno, but again for arguments sake, I track soles the car before and after 0-60 1/4 1/8 and I gained time from my after market downside and mufflers
Do you even own an 15 ecoboost mustang slow?

And if you know so much, where were you a month ago when I posted this problem on the thread????? No one can figure it out, except guess what I just did. I removed them and I'm back to amazing for me! Good luck slow
Took it to three shops worked with three amazing tuners, posted on forums took it to ford. Easy answer: "sir there are no other problems on this car" lol
