In nearly every respect, the wire tap box should 'win' hands down over a downloader.

I run a Smarty and a TST Competition box... there is no comparison to the way each of those makes power on my truck. The truck is an absolute pleasure to drive with just the Smarty(SW#5) and DD3's... quick spoolup, great power, nimble in traffic... flip the switch on the TST and it's a totally different animal... very aggressive fueling map, plant you in the seat acceleration.

We have seen around a 30 hp gain by adding a Smarty to a TST Competition, Mach 6's, SP66, HRVP44... each truck is different. TST Competition is a fuel only box and should really benefit, as shown on the dyno, by adding in some timing.
