I’ve had my Jacobs Pro Street ignition for about 3 years. I’ve had LOTS of people ask me if it’s worth the money.. This evening I decided to put if to the test with my G-Tech meter and see if it make a difference in running my 4Runner down the quarter mile.

all ten runs were done within 1/2 hour from each other and all on the same road going in the same direction..

Check out my results:
