I own a 25' Eliminator Daytona with a 502 MPI and a stage I Procharger. I currently run 5 lbs of boost but am thinking of going to 7.5 lbs. (need that extra speed you know) Has anyone done this with a Stage 1 and if so, did you have to change injectors or do anything other than change the pulley on the Procharger and adjust the fuel pressure?
