| They are still around, "Protwins" are an agent and so is Sigma performance.
Find Ultimaps Australian homepage and you can see all the power graphs and stuff (I havn't looked in years thought !).
Basically they make therir chips by getting volunteers to give them their bikes so they can map a "real world" chip for a standard bike.
You can just pop it in and go, but to get the best from the bike have the throttle bodies balanced and the co2 trim done at the same time.
I did all this myself (and Im no expert) and it was a revelation the smoothness and better power. Do you run a 14 tooth sproket up front? This helps as well. |
