Top speed

[stevnoof]

So from what I've read the Eco boost without pp has a top speed of 121mph. Is this true because I was just driving around and was going over 130 didn't look like she was stoppin me at all. The car is a stock manual mustang Eco

Assuming you were in Mexico... The speedo is more inaccurate the higher it goes. Gotta use a GPS or something to really know for sure.

Is it really speed limited that low? I assume a tune removes the limiter?

True I had my garmin goin I didn't think to look maybe it logs tops speed..anyway it could be off it usually says 40 on gps or cruise control when the speedometer says closer to 44 I guess I will have to go faster next time.

Most tuners remove it. I think the PP is 145. It's due to the speed limit of the tires, liability, etc.

The 11-14 3.7 was limited to 115~ I believe as the driveshaft will break at higher speeds. There is a video of it happening. I would guess around 150 but it really depends on gearing.
