    Looking for help in Central FL area

    It happens on the road and on the dyno. Not at idle or in netural. It is not a whistle sound. I have good boost pressure. It sound almost like a bad speedometer cable or exhaust leak. You would have to hear it because it is hard to describe in text well.

    Bumper filler fit/quality

    I just order a front and rear set for my 87 GN from Danko Reproductions Inc. They are the fiberglass version, so I will let you know how they turn out. The price was good compared to others. They are going on a Drag car, so they in fact don't have to be perfect. The ones currently on the car...

    Wrong dyno?

    gnx good price or not??

    Too much money for a driver in my option. The only reason to have a GNX now is to restore and take to car shows.
