I have a few problems that I need a tune to solve with my auto z28
1. My speed O needs to be adjusted due to the 4.10 gears installed.
2. MY shift points are two low like 1500 RPM's out of first
How do I program 93 octane
all on my i-1000.

Please help

93 tune is the diablo tune.
if you dont have the gear adjustments, load the tune then post the backup and last tune written files from the i2 drive/tunes folder.
