cool:thumbup2:

I would like to know how you stack em. I now have the tst powermax3 and i still have the bully dog torque dod i was usin before.. Can anyone show pictures of how to stack chips.. Do you have to have extra MAP harnes or wires or somethin.. thanks

Guess everyone keepin it a secret..

The edge plugs into the vp/map and the smarty only hits the ecm.You can only have one box for the timing.But you can use the extra fuel on both.The edge/smarty works good.The smarty is used with even numbers.My truck likes 6-smarty and 5x5 edgedrag

I see on the list the tst and bully dog torque dog will stack.. Both plug into the map senor so how does that work??

they just plug into one another.
