All I can say is it's a night and day difference on throttle response. For the money it's well worth it. My wife is scared to death when I half throttle now. It's fairly easy to install and took about 30 minutes of which 10 was fiddling with trying to get the plug off the harness. It feels like I added 50 horsepower when all it did was change the throttle response. Great thing is you can turn it to less aggressive modes as well.
