Hello everyone, I'm new to the site, and I just got a 00 lightning, I need some help with Shift kits, and also chips, I'm looking for names, and places where I could get them, looking for a chip that would increase HP, and speed, 140 mph is fast, not fast enough though. Thanx

 

If you take a look around the site and read some of the forums you will find hundreds of posts about what your asking about. You could click on search also and search for lightning and superchips. As far as top speed, if you have your truck redlined in top gear then the only way to increase the top speed would be to change rear axle ratios which will decrease your acceleration some. If your top speed is being limited by a speed or rev limiter then a computer chip will take care of it.
