Hey MMZ, not to sound like I know everything, but how about mounting a G-tec meter inside your car. Find some nice straight smooth roads, and do a couple pulls, no need to pop fuses and other misc. stuff. G-tec provides Hp and torque graphs in their software. I mentioned this to Woody once but he's hell bent on making a full dyno run by tricking the onboard computer...
From your graphs it looks like the ecu might be reverting to a limp home mode for mapping, probably why the numbers are so low.
