So someone has just bought themselves a new 2011 Ford
Mustang V6. With a respectable output of 305hp, it also has a factory set maximum speed. If you want more power and speed, then you'll need to upgrade to the 5.0-liter V8 with a 145 mph limit (which would be our choice). And in a decision that the owner will certainly regret, he decided to remove the factory speed limiter and take his V6 Mustang up to 135 mph. The result? Well, a few things - none of which are good.
