This kit includes a MACSBOOST module Pro and a impeller with the necessary impeller tool.
The module adds tons of power and improves throttle response. The MACSBOOST impeller improves hookup and traction on the water. If you love to pull tubes or skiiers you will love this combo kit.
When you add gobs of torque you need a way to get the extra power to the water. While the stock impeller is fine for stock levels of power and light loads it has ample room for improvement. If you are on a budget and the Stage 2 is out of reach, this is your best bang for the buck modification.
