I used the Power commander 5 with Autotune so the tune would always be perfect. It is more expensive than the programmer used by Sparks but works much better. Everything is included. So close to $2000 worth of upgrades.
The axles are in good shape and are perfectly true. Jose from summers brothers inspected them. I am selling them complete with CV’s. Two have torn boots where the clamp was crimped too tight. They have maybe a couple hours on them.
It also comes with the belt cover that has been vented and covered with Frogskinz. This really helped to keep the belt cool.
$1200 for the Sparks setup
$800 for the axles
Let me know if you have any questions.
