I am running a good set up at this time but looking for improvement. I was able to make 649hp with the tst and 686.5 with tst and pressure. I am looking at the smarty so i can adjust for tire size and add more rpm. Is there a setting for pressure only? I will also be adding a cam and springs to the mix!

 

Smarty doesn't have a pressure only tune. However Smarty/ TST stack is a potent one.

 

What kind of numbers are people seeing when stacking the smarty and the tst. I know every truck is different just looking for some ideas!!
