08 Z06 LS7 big cam and low rpm light throttle surging - maybe mechanical issue??

There's so many of those on the internet.. people get used to driving around all the shitty characteristics, then get on the internet and claim they drive like stock. Let an average person get in them.. that will tell you if it really drives like stock

Detuned, cammed ls7 vette file attached - says 08, but it was an 06... I've found on these more times than most you can play with the etc scaler and min air settings on top of O2 settings and ignition dwell to get rid of most of the cam surge or the feeling of dragging the potato bag behind you... Ignition in general will also usually help, but you'll never be "entirely" rid of it... I've heard of people putting small holes in the throttle plate to fix the air flow disturbances caused by cams, but never tried it...

You can usually also play with the proportional and integral airflow tables for the surging idle - I recommend starting by trying different OE engine settings and seeing how it reacts then you can personalize them by making .1 tweaks....
