Just bought this truck and it came with EFI Live. I got the PC to ALDL cable and a CD. When I installed what was on the CD it asked for registration numbers and i didnt have any. I would like to know what my options are and I will most definatly need guidence when i go to use it. The truck currently has a EFI Live tune on it, so say the previouse owner but I would like to see what else is available. This thing hauls ass but it is slightly difficult to drive gently because its a manual and the throttle is rather touchy. It also dosent make hardly any power till about 2000rpm and then it takes off like a bat out of hell. Anyways, any help would be greatly appriciated. Thanks
