I am getting ready to order a new tuner. The last tuner I bought (04 pred) came with one canned tune. I was looking at american muscle's sct's. What is the differnce between the livewire and the SF3? Is tge differnce worth the extra cash? Here is what my setup will be this summer, 00 gt, 4.10, manual trans, borla S, offroad prochamber, K&N cold air kit, ZEX kit 100 shot. Considering picking up a throttle body and plenum just not sure yet. I like the choice of the three tunes so I can run a nitrous tune, N/A track tune, and a street tune. Any advise?
