The injectors and fuel pump and rails were all stock during that dyno run. Don't recall which fittings needed to be swapped but it wasn't anything major. The car would have dynoed closer to 450 with the new motordyne exhaust. The numbers may have been a tis higher aswell if I didn't run with 305 rears and 20's and 4.08 gearing.
All that has been changed though now
