Need advise on a programmer. I am looking for one with gauges and that wont hurt my mpg was looking at the JWAcs.

Can anyone with any knowladge point me in the right direction. any help is appreciated. thanks

Probably. It would be hard to guess what kind of miles were on the tranny already. I run the smarty jr on tow mode in my trucks that pull that kind of weight. HUGE difference. You will really like it.

New to Cummings just sold my ford with the 6.0 that was giving me tons of problems and bought a 2006 3500 4x4 mega cab with the 5.9 6spd would the stock clutch hold up to the power of the smarty jr? truck is mainly only used to tow a toyhauler weighing around 15k maxed out looking on what to get to help out the truck. Truck is stock now thx for any advise

The DMF clutch is your 06 is not known for its strength, many fail in the 80K mile range under stock power. There are some that go much longer, like my dads 06 has 105K on the OEM clutch and 85K of those miles are with a Smarty jr on SW1. For a 15K lbtrailer you may pushing it with a stock clutch, and a Jr. I agree with cajflynn that the Jr makes a big difference. I ran one for 5 years and really liked it. I used the economy mode for most of the time as I found the towing setting to be too much fuel above 4K feet with the stock turbo. My dad has only ran the economy mode and until he started grossing over 18K lbs never had to back off for EGTs, but above 18K and with steep grades above 5-6K feet the truck is about maxed out on airflow.

What other mods does ur dads truck have

He has a couple of intake mods, but basically a stock truck with a Smarty Jr as far as the motor is concerned.
