Just bought a Diablo tuner for a ls1
very recently, i have now logs on my car and saved before headers....headers soon to come..
First be sure it is a newer tool that can datalog.
If it is on revision 2.XX it cant log, if it is rev 9rXX it will.
If it cant log, you don't really need the cables for now.
For some good GM Predator info, start here, read the stickies, etc:
