hey guys ran my 93 lightning a couple of weeks ago and got a best et of 15.8 @ 86mph. Not to bad for a truck with 218,000 miles on it. I had some free time on my hands so i installed some new spark plugs, cap and rotor, pullies, and swapped the dual inlet/outlet flowmaster with a dual inlet/outlet magnaflow and ran her again and got a new best of 15.39 @ 90.46 mph. Gonna order some longtubes now and hopefully get her into the 14's before she gets stroked:rollseyes
