When I did research on turbo's and for what brands made good power, Mr.Turbo was low on the list. From tuners and other people, they told me of cheap parts used in the kits. Also, from a tunability standpoint they mentioned the kits were much more difficult. Not saying you can't bolt on one of their kits and run. If all you wanted was to have something turbo'd and a have some increase in power, then it would be fine. But for the money you have to shell out to go turbo, I want the most for my money.
I also noticed on Psychobike that whenever someone had Mr.Turbo kit, it would get removed and replaced with an RCC or Velocity kit. You don't replace your existing kit for no reason. Some kits just don't make the power they advertised. Hahn is another brand that's known for not making the power as advertised. Not saying you couldn't, you need to tweak the kits more to get the same as better brands. That's why I sold my Hahn kit and swapped over to a proven brand(RCC).
There is people out there making power with both Hahn and Mr.Turbo, I choose not to use them from what I've read and heard. This isn't hearsay, just what I've come up with. Alot of companies will use Mr.Turbo from the name. When I first got into turbo's, that's where I looked first. Then I got alittle deeper in the game and learned more from the tuners and performace side of things.
