You guys are both saying the same thing but arguing about it.
I personally like TT and use it all the time. I don't see it as a rip off but an add-on to the DHP and HPT programs. Lately I have been using all 3 programs TT,HPT and DHP to look at/change files. Each of them have their own advantage.
From what I hear, Charles (the guy who owned DHP) is developing a new tuning program that he said will beat the pants off all the current products. When or if that will ever come out is the question. Last I saw, the software part of the tuner was already locked down but the hardware part was something he was checking into.
