They've found a large voltage difference between what the EMS sees and what the battery has which is causing the battery offset table to kick in. They also found the oil pump is shot so they are replacing that. They've had to pull the car on and off the dyno several times. The car will be back on the dyno very soon as all of the problems are now figured out.

Here's a "preliminary" pump gas dynograph. Once fuel pressure issues are rectified we will have final results.
