Hypertech reprogram? Performance upgrades.
This is my first time to this forum. I was just wondering if anyone knows of a way to reprogram (umarry) a hypertech or superchips programmer. Another possible way of raising the speed limiter w/o a programmer maybe. I am trying to avoid paying $300-400 bucks just to go a little faster. I have a 2000 Silverado and have started to upgrade exhaust and intake, and am now looking to other means of increasing HP and performance. Any help will be appreciated.
