I bought a JMS chip last month.....one month later it's still not in (been busy w/ the house). I've heard good things about JMS, I've spoken w/ Chris Johnson, and my choice was easy. I'd be VERY happy to get .1-.3 off my ET and 2-3 mph on my trap (wishful thinking). The car just feels like it needs one.....super fast, but driveability wise (idle/initial throttle response etc). Good luck w/ yours.
