How come the smarty doesnt make more than 70hp? Why doesnt the smarty make more power like the comp box like in the 120hp range?

 

this doesnt tap into the vp directly. and really there isnt a def on how much HP it adds it really pulls the throttle response and tq curve sooner. responds great with other boxes and really good with upgraded sticks. I think you will get more out of it when you have other upgrades that will compliment it. other than that you will get around what a non vp tapped power box. but the smarty does more and has more adjustments to be used. sorta grows with you as your truck grows with the bombing.

 

I have a dr performance box that im trying to stack with it and I cant get the box to work. I put an on and off switch on it and when you turn it one it starts to kind of rev up and miss and sound like its on hiting on three cyclenders.I have call them and they cant seem to find what it is eather I have the right wire taped the top one closest to the bloke. Any body got any guesses for me?
