Matt,
TDR member muddymess told me the power pup used timing/duration on tow setting and no pressure and added 30 hp worth of pressurre in the performance setting and 50 hp worth of pressure in extreme setting. I talked to a chief Engineer at Bullydog who told me the same thing without my asking specifics, and also said they use a lot more pressure on the Crazy larry setting. I have never used it myself but have talked to a few who have and all liked it. What I wonder is how so many get away with stacking it(if you can call it that) with so many other modules? I have seen the ramifier which seems to be the most popular and also the quadzilla modules and Juice as well as the TST. That is what puzzles me? Or maybe we haven't waited long enough to see longer term problems with any of these stacks? seems like one of them would be too much pressure or timing to me?? Go figure. My curiosity is peaked. oh oh...
