Default Cam Only A4 critique my numbers and dyno graphs

Well, I finally made it to a dyno to complete my tune. I am pretty happy as the cam is pretty small and I drive this car 60 miles a day. The car drives like stock, sounds wicked when Im on it, idles well and pulls like a train in the upper range. Here are the mods and graphs:

2001 Z28
Auto
3.42
Lid
P&P TB
LPP Headers (wrapped) and Y
Cutout
Custom 226/228 on a 113
PRC Double Springs, TSP Hardened Pushrods
3500 Stall
ASP Main and Alt Pulleys
Gomer's Tuning Skills
372/368

All 3 Dyno Pulls:
3

First and Last Pulls:


Best Run:

Looks good to me for an unlocked converter dyno.

I can't believe how early that cam peaks. Mine is a 224/228 581/588 113LSA and it peaks around 6400.

Numbers look good, though, considering the drivetrain and fairly mild cam.

I am unsure about the amount of timing that is in there, I'll try to find out. I was under the impression that the converter was locked for the pulls, but it sure looks like it was flashing a bit.

Mach, I was surprised also, but we adjusted the shift points to take advantage
