You have a right to your opinion just like everyone else on here...even if it is wrong. In the world of retail consumers rule and that is why most companies work so hard to create brand loyalty. Why, because consumers have the right to jump ship for whatever reason they want to...it's a shark eat shark world in the retail business and you are only as good as yor last sale period...so if I'm hearing you correctly it should be no surprise that UpRev has not done much for the Z, it's a small market if they are having better success with other platforms. Also, if you really understood what most everyone said, UpRev is a good product, but if you are looking for the best performance tuning software they are now number two in that category.
Lastly, if looking cool by sounding fast and shooting flame is your gig then more power to ya...Mine does the same thing but only at speed so if you are lucky enough to be in my draft...you will get flamed when I decide to slow down lol.
