  1. Product exactly as I expected...and service exceeded that! 5 Star Review

    Installing the tune went fairly easy. Putting in the filter took about a minute too. I also recently put on the Roush axleback. I can definitely feel a big difference in "seat of the pants". Throttle response is so much more crisp. I'm noticing the tires break loose so much easier now. That's probably from the exhaust coupled with the low-end torque boost from the Stage1 kit. Do I feel I got 400.00 worth of power. Absolutely. On a side note, the post office delivered my pkg to the wrong address and Mike went the extra mile to track it down so it arrived safely in hand. Thanks Mike! Looking forward to my next purchase... P. Mink
