Just finished a cam/header install on a 00' C5 MN6. I started with the idle and got it working great. We pulled the motor on the dyno with the stock timing table and had zero knock retard. The A/F was a bit rich but damn near matched the values in table {B3618} PE Modifier based on rpm. Can I assume that the IFR (which was stock) and the VE table values are pretty close? After seeing that they where close, I leaned down the PE table and got the AF where I wanted it. My main question is back to the stock timing table. If the motor didn't mind the stock timing table, should I call it quits?? The timing ended up around 28 degrees at full advance for most the WOT range. The car made 388 RWHP and 370 RWFT which I felt was pretty good with the stock heads, cats and stock LS1 intake.

What do you guys think? As a newbie I finally felt like I got a grip on this tune as it only took me 4 flashes for the idle and 3 for the WOT! LOL!! :lol:
