Need Help with 2001 8.1 Allison

[mbrax209]

2001 Chevy Silverado 2500hd . 8.1, Allison. K&N FIPK and Open Exhaust.

Using Intune I1000, tuned truck. Motor runs fine, however when tuned the transmission does not shift properly. It shifts better with stock programming.
It shifts very soft and slow with delayed shift compared to stock settings with intune Programming. Using your canned tune.

Truck's is used for day to day driving, with occasional recreational use towing 5th wheel camper. Camper weighs 11k.

Looking for improved shifting, towing and better fuel mileage. More HP and Torque for towing.

Thanks

Mike
