Customer Testimonials

Patrick - 2008 Kawasaki ZX-10R - Fenton, Montana

First I’d like to say “Thank You Jeffo” for all your assistance! The customer service that Jeffo provides is phenomenal! I myself was skeptical about purchasing a map file from the internet… But I am so glad I did! And for only $50. Jeffo sent me the map and explained how to set everything up like the Throttle Position, Accelerator Pump Utility and loading the map on the PCIIIUsb. When I got it all hooked up and got to ride my 2008 ZX10R it was awesome. The smoothness of the throttle is so user friendly, the gear changes are without jerks or jolts and it runs so much cooler. It is like having a new bike all over again. Thanks Again Jeffo!!
