Ford advertises around 5.5 seconds 0-60 for my 2014 3.7L mustang.

My car has 54k miles but has been properly serviced all it's life. I have installed a Roush CAI, BBK 73mm Throttle Body, and a new 91R tune.

I have done several 0-60 runs and the best i've gotten so far is 6.6 seconds.

This seems really slow considering the bolt-ons... and the 91 octane race tune. I do have my spare in the trunk but that shouldn't make me a second slower.

Is there a reason why my 3.7L automatic 2014 mustang is 6.6s 0-60 with several bolt-on mods?

Auto or Manual? What gears do you have?

It's an automatic with stock 2.73 gears ;l

Well there's your reason, I guarantee that wasn't the setup Ford used when they got those #'s. If it was a production car at all lol.

They all do it.......

Just changing the gears to 3:31 or higher will get you under 6 seconds, American Muscle got their under 5 seconds with a few bolt ons, its posted on their website.
