On the run from 70? He might as well been parked...stock IC was probably heat soaked from even part throttle driving at that speed.
With work done and stock IC and turbo I was almost at 0 vac. at 85 MPH cruise. Maybe you should catch him at a light before you claim victory (not that I have any clue what your car runs).
