can you post your current file as well as some current scans with this happening?

ok i will do that but first let me pot the toruqmanagment back and see.

Don't confuse torque management with torque reduction. The latter will pull timing during the shift. I'm sure they're related in other ways, but you can still have reduction without management.

My advice would be to enable the torque management, but increase the allowable torque.

Are you seeing any KR?

Did you increase the max engine tq?

Its under Engine-Torque managment-general-Maximum Torque

You might even try heading over too PerformanceTrucks.net also, there are a lot of MagnaCharger guys over there.

ok what i did last night was i put the torque mangemant to enable and the car still pulling some timing and i dont see any KR at all and thear is one thing that i dont understand is thear is no reading for the oxsgine sensers and when i looked under the car to check the O2 i couldent finde any sensors on it dose that make that problem and even the plugs for it some peopel told me that model dosent come with O2.

What i did yesterday i open the car file to see the high octane and the low octane table you can see there is numbers -3 or -6 and more than that.what i did is i pot thease number to 4 and 6 and more than that and the car start to be good and when you run the car on the dyno the AFR stayes at 15 it dosent what to add fulle.and when you levet it for lat say 30mints ant start the car againe avery thing gets back againe.

technical

The O2 sensors are there....or you have big problems. You might be seeing issues when the vehicle gets to a certain temp e.g. IAT temp gets too high and the PCM begine to pull timing. Sounds like more than just one or two things going on.
