Using HPT? I have ruled out several items in the process of trying to fix my brothers car. The following have been checked, swapped and verified to be ok:
Tune, PCM, Coil Packs, Wires, Plugs, MAF, TB.
This leaves me to fuel pressure and Injectors. Getting a rail pressure gauge today, so want to find out if HPT has a way to cycle injectors or something. I did not logging that B2 is always substantially more then B1 reading the IPW.

The cylinder balance test may give you an idea if one of the injectors is faulty
I try that and the car stalls. I finally got it to Idle, not sure how or why, but not really questioning the anomolies anymore. The little bit of the test I did get done holding the throttle off at 5% TPS, showed a pretty good balance.

You best bet is if you know anyone with a Tech one.. or just unplug them one at a time and see if it makes any difference, we were able to find one back injector that I got with this method.
We went back with my buddies tech one.. it is the best way.. you can switch on and off each injector as you wish.
Hope that helps.
