Thread: Gen 1 or LSX?

Yeah, the learning curve on the tuning electronic gear can be daunting. But enough people are doing it that it can't be that bad. Since I don't plan on changing mine up much, I paid a local tuner to do a "Drivability Tune" on mine. He came to my house and we drove around for 2 hours with his laptop plugged in. He would tell me to do something and observe what the motor was doing, then we would stop and he would make adjustments to spark curve or tranny shift points. Then he stuck an air fuel sensor in my tail pipe and drove some more and he made adjustments to the injection. The car drives like a dream now and is super responsive and quick. He also made sure it was a "safe" tune by not letting it get too lean. All these things we used to do with jets, timing light and advance curve while reading plugs.

Transmission bolt pattern is the same for previous Chevy Transmissions. You may need a spacer for the flex plate to run a T350, T400 or Glide. If you are going manual, no reason not to use the T-56 6 speed. If you are building a super strong motor and want an auto, then the 4L80E is quite strong and probably what would come with a 6.0 pull out from a truck. If you want to get real exotic, they also have strong 6 speed automatics now too.
