I don't know much, but that "Street O****w no prep stuff does not really reflect drag racing for me. I am no racer by any stretch; most I ever did was run 1/8th miles at Coastal Plains Dragway in Jacksonville, NC. I had an 87 mustang LX, 5.0. Did some things to it, would go out on Friday nights with my Marine buddies; the crew. 1st pass, a high school Vocational tech teacher; nice man. He had a 91 mustang. Pretty humbling as he walked away! Then he came over with his students, gave us some pointers and we kept improving. Now that was racing; I was only 23 at the time. Next pass was faster; but a pinto wagon blew my doors off. It was simple heads up run what you brung. It was fun, best part was realizing how little I knew and how every part of the car has to be working togther. I thought drag racing was intended for average guys like me. I really like watching Southern Gassers association on you tube, the original drag racing captured on super 8 from all over the country. Like old stock cars. I still believe tune ups should require a great ear, timing light, vacuum gauge and patience. I use computers every day in repairing marine diesel and gasoline engines. However the ECU don't tell you everything, sometimes nothing at all. I am fortunate to have been exposed to all the "salts" that taught me the ins and outs of carbs, breaker ignition, basic machine work and proper diagnostics. But tuning with a computer? Really??? Come on...
