I am a technician in the automotive field and have tried many carb jet kits. The Dynojet Thunderslide [kit] is a great product. Easy instructions and it will definitely increase the speed of throttle response. Better performance through the entire power range.

This kit made a very noticeable improvement. Throttle response and acceleration are awesome. I have not measured mileage yet.
