Thank you for accepting me on your forum. I came here from the driveway engineer. I have a 2001 tahoe 4.8 ls and several trailblazers with the 4200.
I am now too old for quad racing but too young to give up on the thrill of speed and torque. In the planning stage of making some power on the ls and also the 4200.
Came here to learn about the how to's on programming your stock ecu and check out the community and all projects :)
