Guys, new to the forum and EFI tuning wasn't sure the best place to post these questions. I've read thru the tutorials and think I have a good idea of what to do but like everyone else I need some quick wins to boost my confidence. I have an LS6 in a 05 CTS-V, my questions are:
1. Any custom OS templates available specific to this engine?
2. Do I NEED a WBO2 sensor to create a worthwhile tune or can I start without it and add it later once I get more experience?
3. Any advice on what to go after first for those quick wins? I'm looking for increased throttle response and HP of course but need daily drivability.
My car is stock except for CAI and Catbacks. Thanks in advance for any helpful tips or advice.
