    Go to your.......Torque Management Table-General-ETC Limits-ETC TPS Max, on this table you have set everything to 0 why is that? you want this table at 100 not 0s, also the table below that one its called ETC injector Disable, you have that one at 0s also , that means that the computer its going to completely disable all cylinders any time it applies torque management witch is when you are trying to power brake it, change that one back to stock or if you want to disable it just set it to 255, also in Torque Tanagement-Abuse- Drivetrain Abuse- change the rpm to 7000 and the mph to 5 mph, that will disable the drivetrain abuse table, try that and see how it works for you, in the future before you change any table to 0s hit the F1 key and see what the table does and what numbers you should put in there, 0 does not always mean disabled and you can create a lot of problems by doing that, be careful
