I have been working on a towing tune for my 2004 Escalade ESV. The Engine is currently stock 6.0L, electric fans 4L65E trans, LQ9 and the trans has vette servo and OD billet servo, HD Assembly band and new assembly set. Towing will be 24ft enclosed trailer with Corvette and extra set of tires. Total weight varies between 7500 and 7900 lbs. Major problem is the 3-4 up shift and down shift. After much reading and searching I have made the following changes. Tomorrow I plan to load and log going to pick up the trailer, returning, and short run with the loaded trailer. Before I uploaded I was wondering if anyone sees any immediate problems with the tune.

The trans kick downs and downshifts were basically copying Performance to normal and moving up two cells. Also 15% TM was removed.
