I have a k-tuned speed converter that works but does not do enough percentage change from low speed to high speed frequency. This unit was only used for troubleshooting. It is in very new condition and comes with everything it would if you purchased from k-tuned themselves. Price is firm and USPS shipping is included. K-Tuned will charge you for shipping.

Only PayPal goods and services for payment as it provides protections for us both. Friends and Family payments will not be accepted.

I am happy to answer questions.
