Yes. Unless you change to the the TT Fuel Pump Controller ( and Wiring Upgrade ) you will need to run an NA ECU ( 8 bit or 16 Bit, your Choice ) with the CAR.. the Program needs to match the Engine and accessories. IE AIV's, Injector Size, intake Mods ETC ... I'm unclear if the NA ECU has the Outputs to drive the Boost Sol, so that will have to be adressed. The TT program will have the ability to control the Sol, but I do not know if the NA ECU will have the output to do it..
