Take It to the Max! The History of ThunderMax®
Today, electronic fuel injection is considered to be the industry standard. Many companies have been advertising different types of post fuel controllers as performance solutions. However, one solution that has outpaced all others in true performance since the early days of factory fit EFI is the ThunderMax® EFI System. Engineered by Thunder Heart Performance Corporation (TN, USA) and developed by Zipper's Performance Products (MD, USA), the ThunderMax® EFI system has changed the way consumers ride fuel injected Harleys®.
Talking about Thunder Heart Performance and Zipper's Performance Products working together on the ThunderMax®, Dan Fitzmaurice says: "Our alliance with Thunder Heart has allowed us to combine our aftermarket engine experience and performance tuning expertise with Thunder Heart's engineering and manufacturing capability. Zipper's decades of brand equity, revolving around our reputation for high quality, proven results, has helped us successfully market the ThunderMax® brand and turn it into a household name."
