My advice...

Read. Read as much as you can read up on from the DIY guys for LT1s, wherever those forums may be. I suggest having a full comprehension on GM engine control as well as what makes an engine produce more power. If you in anyway doubt yourself in any area and cannot find an answer, I would advise you to stop before damage occurs.

i'm not playing with anything, i basically got the program just to change my gear setting. It cost $110 for everything and can do so much more the $340 hand held hypertech tuner. It does scare me though.
