Hi Steve,

its not just about the mods you are doing , but the way the bike runs from factory. They are generally lean and can do with a richen up in various areas of performance to improve.

Everyone will have their opinion on which tuner option is better, and running the right AFR etc. The bottom line is you need to do something. ASk yourself what you realistically see yourself doing in the future and that may make your mind up for you. Minor tweaking, or major mods. Then ask specific questions about how the various units operate and make an informed decision.

Kind regards

Mick
