Testimonials

Recently we’ve gotten some positive feedback we wanted to share:

“Thank You for the prompt reply and formulas you provided, now onward…….. Just want to tell you how much your books helped me in the tuning area. The reading was technical but interesting and informative. I found myself reading each chapter twice before moving on to the next as it flows chapter to chapter. Now I understand why and how the different aspects fit together and can make better calls and decisions. The 5000 Horse Power On Methonol book goes with me to the track so if need to, I can use the
formula’s and figure it out long hand on paper. Looking forward to positive results.”
