I am new here but i have been reading posts on this forum for at least a year now. Looks like a great bunch of people and I can't wait to join in, finally!!! I have an 01 Tahoe 4X4 5.3L, I bought it in 11/2000, and have been waiting ever since to start tuning it. I just placed my order what a great feeling, I just hope I get it soon. All the excitement on this site about this product has me dying to get tuning. Hopefully I can be of some help as well. All in all I will finally be a fellow tuner, and I just wanted to say hi and introduce myself.
