Welcome to TheFastman.com!

Modified Throttle Body Specialist

Please note I am CLOSED. I am taking my annual Fall hunting break. I will answer the phone and emails when available. I will still trickle out work when home but at a slow pace. I will reopen fulltime Mid Nov.

My reworked factory TB's will bring out that hidden performance you are looking for. Most engines are restricted and the addition of one of my modified TB's will let your engine breathe. They are one of the simplest and most effective mods you can make to your vehicle. My modified TB's have set the standard in the industry in both quality and performance. When you go with a Fastman Modified Throttle Body you install a product that delivers.
