I just installed some Reverse Glow Gauges on my V6 (http://www.mustangtuning.com/99-04-v...low-gauge.html). Well when installing them I needed to remove my needles to put it on. Well all the needles work fine but my speedo says I am going 5 mhp faster than I am going, I've taken it back off and put it back on a few times and no matter what I do it still says I am 5 off. Is there a better way to go about fixing this or am I going to have to just live with this problem. Any info would be great.

Thanks,
Mike

 

Keep them hooked up but just kinda sitting close to the stock location with no gauge cover on it. Get going about 20 or so along side of a friend and stick it on.
