Hypertech Tuner Questions...

Can't help you on the shift points. As far as the gas part.... regular gas would be 87 reg/ mid-grade 89 octane and non regular would be premium gas 91-93 octane and above. Unless you are heavily modded/high CR motor and require 91-93 and above octane ...don't use this mode. Use the regular setting.
This is a high performance motor, and was not designed to run 87 from the factory, so I would choose the high octane tune.
Also, you will see better performance gains from the higher octane tune generally.
FWIW, i ditched the handhelds and just had a shop do tuning with hptuners / ls1edit and have never regretted the decision.
