The mini rude and XX are the exact same supercharger and both will make more power than any of the other X model supercharger upgrades.

The problem is your stock ECU has a boost limiter. You will need to go with this ECU reflash to see the full potential from a supercharger upgrade

I have the same ski with all the RIVAS stage I stuff installed. Current speed 73 MPH. If I change the SC to the Mini Rude or XX as suggested and have my ECU re-mapped, looks like valve gear upgrade is a must, what increase in speed can I expect? After the re-map does the ECU just plug back in or do I have to have the system hooked up to BUDS to make it work? And... can I keep the stock injectors or is there additional modification to the fuel system that would be required? Thanks, just trying to understand this stuff before I jump....

With the ECU reflash the Riva valve train upgrade it a must. The ECU will be plug and play once you get it back. No need to hook to BUDS. The reflash is for the stock injectors, no need to change those. The reflash can handle the boost of the XX or Mini Rude.

You will easily see speeds of 76+ mph with lots better acceleration.

Hope that helps!

oh, turn around time has been running only 1 day from the time they receive the ECU.

To do the valve train upgrade, does the head have to come off?
