Need a tuner. I didn't want to get the ls1edit, because of the learning curve. Heard you can really mess up things with it, so the predator was a good option for me. However and option that does not exist for a 98 LS1. What is the next best thing? Hyper tech I hear are hypercrap from some of things I've heard.

 

What do you want it for?

Ls-1 edit is the best option, there are people on the boards willing to help you learn.

Other option take somewhere and get it dyno tuned.

Good Luck
