Dyno results (Long)

Okay, here are the results of my Dyno runs tonight.
1st run: Timing 16 BTDC; MSD BTM set to .3; distributor retard unplugged (I forgot to hook it back up after changing timing!);
Max HP:184.9 @5400 rpm; Max Torque 236.5 @4000 rpm
2nd run: Timing 20 BTDC; MSD BTM set to .3; distributor retard unplugged
Max HP:185.7 @ 5200 rpm; Max Torque 210.5 @3900 rpm
3rd run: Timing 20; MSD BTM set to .3; stock distributor retard plugged in!
Max HP:204.5 @ 4400 rpm; Max Torque 246.3 @ 4300 rpm
4th run: Timing 20; MSD BTM set to .5; stock distributor retard plugged in
Max HP:174.1 @ 4500 rpm; Max Torque 209.7 @ 4000 rpm
I was just playing around the 4th time. I would need another 4-5 runs to figure out the perfect settings for the MSD and stock retard.
In every run I dropped down from 25 psi to 13 psi right around 4500 rpm, except the 4th run. The 4th run stayed pretty consistent all the way up to 5,000 rpm. On the highway I noticed a similar behavior around 4500 rpm. It dropped down to 18 psi, but nothing like on the dyno. The funny thing is that after 4,500 rpm, the boost would start to come back up full.
It acted like the engine pinged. With all runs, the Air/Fuel mixture was 3 bars in the green.
I'm going to put in the Swedish Dynamics "Red Cams" and go back down. Hopefully next week sometime. I gotta get this testing done before the snow flies!
I'll try to get a digital pic of the graphs and post them on the website.
All comments and questions welcome!
