Master Technician

A Word From Josh

Thankful for all my accomplishments, and most proud to have served as a United States Marine.  Being a Marine was a childhood dream.  Approaching my discharge, I knew what was next purchased my first Harley Davidson a 2003FXSTB, Nighttrain.  Then on to MMI, Orlando, FL to complete their Harley Davidson Technician program.  School was a struggle, but with my supportive loving family, of course, we achieved it.

My motorcycle technician career brought me to Texas and its great working on Harley’s makes m happy and I’ve accomplished so much in performance engine builds that every day is an adventure.

Top Dead Center Performance was born, where the customer’s concerns are always #1.  It was defiantly the right decision heading out on my own away from the corporate dealership. With support from a dear friend and my loving family, I strive to never quit or give up.

After working hard and reaching Master Technician level I wanted more.  The dealership sends me the best customers!  Your Harley Davidson’s maintenance and care is our number one priority.

Come see me and check out my  2003 FXSTB, Nighttrain my pride and joy. The engine built in 2005 it was exciting and eye-opening to the world “Aftermarket Performance” products available they exceed the “Screaming Eagle” products by far.  My Nighttrain’s dyno chart on our blog, putting down 131HP & 131TQ!!
