Just a suggestion, the stock rev limit in neutral on my 2010 camaro was 4000 RPM before Mr. Lew changed it for me, and the rev limit in gear is 6200 RPM ...
i dunno why GM would make it that much of a difference, if the engine doesn't blow at 6200 while in gear, it shouldn't while in neutral!
i suggest this should be an option, to change the "rev limit in neutral" to a certain degree on the programmers in the next revisions!
what do you guys think
