Can I stack these somehow??
 

Hey guys I have a tst power max3 and a power puck,,now my buddy's got a smarty and wants me to try it out..can I stack all three or what would the best route be to go??currently I run the power max at #7 with the power puck sometimes #9 when needed....

the PM3 and Smarty Is a hell of a setup and should run better than the puck for sure. Smarty and the puck both do timing so if you do want to run all 3 you HAVE to have the Smarty on an even number so it doesnt add timing. I never liked stacking more than 2 tuners though but you can try it.
