My tuner has my 212/218 loping as hard if not harder at times. Pretty sure its no tuning secret

 

seems to hit at a pretty stable rate, i'm guessing this is what your referring to? That cam should hit pretty hard in a 5.3 on a 112lsa, did you ever run it before you worked the magic? its not exactly a small cam for a 5.3, just a little low on the intake duration.

 

Yeah it cut up a little without the idle tune, but not nearly as much. It didn't really have a lope to it without it, even on 9 degrees of absolute timing.

 

Dont get your panties in a twist, I prefer a smooth idle.

I just didnt know what I was supposed to be looking/listening for in the the video. You just said "here is a video of my cam/exhaust with some secret tuning", so I asked what I was supposed to be seeing....
