what are some good tuning programs for the 2000 vortec 4.3L? I've heard alot of the 4.3 guys use a program called tuner cat and alot of guys on here use HP Tuners or EFI Live. what are you guys opions on the different programs and how easy are they to learn?

i dont believe hptuners nor efilive work with the 00 computers...they work with 01+ mainly because they are identical to LS1's. Bottom line is currently your only option is tunercat :(
