FUN Facts / What MAKES MPT DIFFERENT?

26 Fords

26 and growing is the number of Fords owned by MPT employees. We own, drive and tune our own vehicles just like you. Our company mission statement is to treat customers how we want to be treated. It's an easy win for both of us.
In-House Dyno

We are a performance shop, selling parts and accessories, but we are also a dyno shop. We develop our tunes in-house on our dyno. Making sure everything is perfect before we sell anything to our customers.
We own, drive and tune our own vehicles. Some tuners out there don't have a shop, don't own a dyno, don't pick up the phone and don't even drive Ford Vehicles. Ask yourself how they test and develop tunes.
My name is Mike Thornhill, I'm the owner here at MPT. We've been tuning Fords for more than 15 years now. This is what we do, day in and day out. Tuning and performance is our specialty. I know some people might be new to tuning and may even think it's snake oil. I can tell you after one minute of driving, you will know the MPT difference is very real. I encourage you to read reviews, browse this site and don't hesitate to contact us for any questions you may have. Thanks for checking us out. // Mike @ MPT
