I'm Awesome
When I was having some performance problems with my 94 GMC k1500 that I couldn't solve, I took it to a good mechanic up in the foothills. He is a former GM mechanic at a GM truck factory. I had put quality non-GM wires, dist. cap, ignition module, etc. on it as the original owner had not tuned it up at all after 125,000 miles, was all original and basically ran just ok. However all the new parts I put on it didn't seem to help at all and maybe ran a little bit worse. He told me to ALWAYS use genuine GM tune up parts for the ignition system. So, did and it ran much better.
