I've seen a pulley chart on here for rx-1 and apex setups but none for the Nytro. Does anyone have the ratio chart for a mpi stg 1 nytro? Wondering at sea level what pullies equal what boost? I do have a head shim to lower the octane, and the pcv switch to adjust maps for octane needs. Mpi seems to only know this for elevation from conversations I've had with them. Thanks for the help guys ;)!
