Why not use TunerPro to datalog? It may give you more readings.

Yor TPS could be a couple points lower, I think .54 or .55 would be better. Have you cleaned the iac valve? I have seen it cause idle problems.

This thread lists the BIN locations to change for SA & PW. You will need to calculate injector DC% from RPM & PW manually.

To edit in hex use TunerPro and open the BIN in hex format ((Tools->Advanced->Hex Editor). Then go to the location listed, verify the current values, and edit in the new values. Then save.
