Just got back from the Mopar Fun Run and car show at Farmington Drag strip in Farmington NC. I was able to win a 3rd place award in Dodge trucks of all years out of about 50+ trucks. I ran 4 consistent 1/8 mile runs of 9.3 which was a little disappointing for me when I was running 9.1's and one 8.9 1/8 at another track 3 weeks earlier. I tried it with my throttle controller on full race mode and ran 2 runs with a 9.2 before we got rained out and didn't get to run any more. My truck runs different with the throttle controller, I've tested it enough now to where I'm not going to discuss it anymore. Buy one and do your own test with your truck.
