Here is a completely warmed up video clip of the Beer:30 cam.
Sound doesn’t mean much to me, I’m a performance guy.

This one here has both. Graphs to be posted soon!

Up from slumber, like a kid at Christmas!

After months of denial, I decided to join Techno Research, in the quest of the perfect Harley tuning system!

I’ve heard so much good about it, from friends and fellow Harley dyno tuners about the power and consistency of this system!

It’s been a few months now since Stephanie joined in on the family business, and she is killing it!

I’ve always dreamed of her taking over our family business, and now it’s coming to fruition!

Going to be a while before I move over and fully give her the reigns, so to speak.
One thing she has done is made it fun for me again!!

Love you girl❤️

Everyone please welcome the newest member of the Sheffer Performance Team.

Stephanie Sheffer Davidson!
She is our daughter and is excited about this new chapter.

She is currently handling all aspects of our website, answering phones, emails and such. Also is going to be trained in every aspect of what we do, including comprehensive dyno tuning.
To say I’m happy about her involvement in our company, would be a huge understatement.
