11/10/01 Dyno results
I dynoed the car again at Turbo Technology Inc after tweaking the MAFT to dial in the ZO6 MAF correctly.

I made a total of 4 pulls, the first run was made without using the extra ground wire required by the LS1 PCM so the tach on the dyno didn't read correctly.
On the 2nd run, the MAFT was set at +10% rich base and 2%lean WOT netting 298 RWHP & 306 RWTQ
The 3rd run had the MAFT at +10% rich base and 4% lean WOT netting 300 RWHP & 315 RWTQ
The 4th run had the MAFT at +10% rich base and 6% lean WOT netting 300.5 RWHP & 313 RWTQ

The best results really are with the 3rd run based on the torque. The 300RWHP - 315RWTQ run is a net increase of 13RWHP and 15RWTQ from the last dyno session so I'm very happy with the results.

Phase II next steps

With Phase I now basically complete, modifications of the LS1 in pursuit of more HP will begin! The following items are on order:

MTI "B1" camshaft & kit - 222°/222°, 0.559"/0.559" @ 114° C/L
LS6 intake manifold
ASP crank pulley

This should take care of the intake tract. I will also look into a ported throttle body. Installation of these components should take place over the Christmas Holiday!
