I just did the update on my predator, is the torque modulation parameter used to turn the torque reduction off? Also can someone explain what the MAF curve does? Thanks

 

Yes, that parameter adjusts the amount of torque reduction present in the tune. If you leave it alone, it retains stock settings. I'm sure you know but just in case... Since you've got a valve body, the recommended action is to leave it alone.

The MAF function adds or removes fuel from the entire curve, globally. I personally wouldn't mess with any of the gas regulation features without at least a wideband A/F gauge in the truck.

 

I thought thats what the MAF curve was for. Thanks
