pressure sensor and pressure release question
 

okay i have no emmissions on my car and i took off the omp and im running premixed. i have a bov, do i need the pressure sensor and the pressure release valve? i prob need to keep the pressure sensor but im not sure. any one have a bov and keep there old system?

You want the pressure sensor for its timing retard function in the ECU.
Also to avoid a check light.

When you say pressure release, do you mean compressor bypass valve?
If so the atmospheric BOV replaces it..
