just my opinion here, but "not for the faint of heart" is like universal truth number 19. Do you really know what these boxes do, and do you understand the consequences of putting them together? I mean, by all means do the smoke test if you want; I'm as curious as the next guy and would be on the side lines watching, but if I were you I would want to understand the timing advance acheived by this combo before burning holes in my pistons with some unknown, untested radical timing advance produced by the additive combination of two boxes, each of which was designed to explore a responsible limit.
The Bullydog advances the stock timing inside the ECM to get a bit more power and to reduce EGTs. Now you put a TST box on top of that which will perform analog time fooling in ADDITION to the Bullydog ECM-level timing advance. How far do you want to advance the injector opening and how much advance do you think that combo gives? and if you want to go that far, why don't you think eithier TST or Bullydog did it themselves?
this isn't a personal criticism; just a nudge to highlight a consequence you might not have otherwise considered. -doug
