I have an '87 GN that was built for speed but needs a good tune up to bring it to it's full potential. I'm located in central CA near the coast but could trailer the car any reasonable distance. Does anyone know of someone In CA that knows GN's and could tune this car for me and get it running in tip top shape? The local speed shop is just not into GN's. Please let me know if you know of anyone. Thanks, Rick
