I've had both. Currently have smarty. What does that tell u?
I guess it really boils down to what do u want?
Option 1. H&S- bling factor, only 4 gauges at once, defuel capability for those of us that have no self contol over their right foot, serious amount of duration and smoke. Now they just added timing and dp for gauges, which i have to say is badd a$$. Higher egts due to the lack of timing added. Do also have od tuning for ur tcm.
Option 2- smarty. Cleaner power using less duration and more timing, lower egts, user end adkustibility is the big diff. I can chose from 18 base tunes and then modify my rail, turbo, timing, and torque settings on each tune. No smoke unless i want to turn it way the hell up. It is faster than h&s. Atleast on my truck.
Smarty is kind of all buisness, where h&s is more, here's some cool power, good mpg's, and a cool programmer to mount in ur truck with a safety net built into it.
It just depends on what u want to do with ur truck. I started with h&s, and switched to smarty due to the ability to black out 4 lanes of traffic. I picked up the cts monitor for all but two of my gauges, bout the same price as a blackmax. I love it.
Like i said, up tp what u want. Best thing to do is find someone local, or at an event that has both and see if they will take u for a spin.
Both are good tuners, just different.:thumbsup:
