I am considering getting the supercharger when i get my new tc. I'm really curious to see how much power this things going to make though. Do you think toyota is underestimating the gains to be had with it? only 25% gain is low considering that the hp is only 160. I seem to remember seeing somewhere that max boost will be 5psi. No problem excpet that others are making far more power from 5psi. is it because its not intercooled? Because there are no computer changes involved/no upgraded fuel components.... or mabey all of the above???? id personaly like to see more improvement from this kit.. somewhere in the area of 220-240 hp. What do you seasoned guys think?
