What is your spark set at with your Predator?
I can do the plugs after I put some miles on them but I am pretty sure that they are gapped all over the place like my previuos LS1'S.
I don't really know what the predator has my ignition timing set @. For now I just installed the preprogrammed tuning set-up. Once I get my CAI put in, I'll have the guy that I bought the predator from do a custom tune for me. When I bought the Predator, it came with free lifetime custom tunes.
I bought from a guy that a number of people in another forum have been using. I think you know who, and which forum, I am talking about.
The custom tuning thing was the selling point that pushed me over the edge, and got me to buy the tuner.
One thing I have noticed, and I think it's cool, is that after the tune, I can now use the engine for more engine braking. It seems like the engine is more responsive - "Tighter" is a word that comes to mind. It winds back down much faster after revving in neutral from an idle. Most of the popping noise on decel is gone when I let off the gas pedal. Overall it just seems smoother and more controlled - hence "Tighter."
Sorry, I guess I'm rambling. I look forward to hearing what you find out about the wires.
