Need Help with TM on 2009 4.8L Pickup

[Performance SS]

Been tuning LT1 and LS cars for some time, but having difficulty with a friends 2009 4.8L 1500 Chevy Pickup. It will not spin the tires no matter what I do. I have tried several different attempted modificiations to the TM tables in both the Engine and TCM with little to no success. Not familiar with "Tip-in Torque Reduction (ft-lb) Vs. Torque Vs. TPS for all gears. Do I zero these tables or max them out to get rid of TM. I'm using TunerCat, anyone with a .cal file with successful TM removed would be appreciated for comparison or steering me in the right direction.

Thanks

Would it be possible for you to post the original / stock unmodified .cal file?

Dave - Thanks for your respone. I'm currently at work, will have to get to tuning laptop so that I can upload .cal files. Will do so then.

Thanks again for any assistance.

I hope I did this correctly. I attached the two files in stock form.

I have downloaded the files. I'm more familiar with the the Before 2007 LSx systems. I'm sure you have already tried the setting in the picture below?

I've tried several combinations, but I'll go over those settings once I get the truck back and try several things again. I just hate trying without understanding the function. Naturally that's usually the way we have to learn with trial and error, but TM has so many variables that lend to the possibility many combos and errors.

I looked back at what i programmed. I had the Calibrations Options as you noted, but I didn't have the TCS Enable temp maxed out. It was still at -40. That would not allow TCS even with it ON, I would assume?
