what kind of ECU mods requered afer a t/c intall? I'm not sure of what turbo kit to install, but I think is going to be the Greddy or the APS one (waiting to see APS results and opinions.) I want to install the HKS' Vein Presure Converter, Electronic Valve Controller, and the F-Con V pro. Is this possible with that turbo kits? I think this will make such a great work of the turbo Has anyone done this before?what are the results?

THANKS
