Yes... so i just got my new laptop and the tuner will be coming in a few days. I am looking forward to adjusting lots of stuff... once i get it here... ill be doing alot of reading on it and studies before i get to use it.... it will be the last thing being done to the car. I am looking forward to showing you all pics and stats as i go. I know im prolly not the only one doing this right now... im sure there are a few people working with the tuners right now so id be glad to hear anymore input or tips on it... there is not much on here yet for the tuner yet... i have not looked over J-body yet... but will be doing that tomorrow since i have the day off :D yeah!
