Towing performance chips

[patrleach]

I have a 05 4.0L XLT 4X4 auto, 3.55, are there any towing performance chips or upgrades to increase the towing performance? It tows good but I'm never satisfied.

How much, if I may ask, are you trying to tow?

I tow a 19 ft bass boat total weight around 3500.

I would recommend an SCT X3, you can purchase here.
