Those that have tuned or programmed
My Smarty programmer has economy, tow and performance settings. My question is, do you all tow exclusively in tow mode or any of the other 2?

Super Dave… Hopefully you have a pyrometer so you can watch the exhaust heat. Is economy less power than Tow? Tow should be safe so start with that but I would also try economy, just out of curiosity. I had a Diablo sport stack on my 03, 6 speed truck. Tow was 60 and economy was 100 hp. With a bigger towing turbo and all the air and exhaust mods I could run the 100 easily. The 100 was actually a better towing tune than the 60 and i got better mpg with the 100. Wwatch the gauges and try economy and tow and see which one you like better. Watch out for clutch or transmission slipping and also see which one provides better drive ability. Craig
