ive just discovered this unit and cant really find alot of info in it here? does it replace the stock computer? price? how hard is it to put in? tuneable? any input would be great thanks

The unit you would want is 950-101. I googled for prices and Amazon has it for $100 less than Summit/Jegs. So, if you order from Summit, they will beat the Amazon price.

Installing it is fairly easy since it includes the wiring and sensors that you need. Tuning it is simple once you understand the basics. The manual is a great guide and can be downloaded so you know what you are getting into before you purchase.

There is not much info on this site, but if you browse chevytalk.org a lot of people are using the system there.

seems like it would be a good system if it also control the torque converter lock up...
