Just got my car back from Erik at Sport Purpose Garage who installed and tuned my Clewett ITBs with Masters ECU. 160 WHP but way, way better road manners and torque, especially at partial throttle. Super super happy with how this turned out versus my old Webers.
If you're looking for someone to install and tune one of these setups, I'd highly recommend him. Super communicative, works very fast, and does fantastic, clean work.
