Hi everyone. I bought a 2016 focus ST last year that already had a custom big turbo tune on it. I recently had to change a few parts on the car and it was running like ****. So I started doing some research on tuning companies and came across Monster Tuned. I highly recommend him. From the first email to the last email he was very helpful and friendly with all my questions about what was going on during the tuning process. It was the first remote tuning I have been part of and I feel it went smoothly and my car is definitely running way smoother and faster then it was on the old custom tune. So if your looking for a custom tune atleast look them up and ask some questions on their tuning process.
