what have you found the most effective way of bypassing the maf sensor? I have the turbo in the same place as the c1j a 3" turbo inlet (all i could get) then a 45degree bend then the maf and a filter. I was thinking about getting a 3" dumpvalve fitting t piece to go in the 45degree bend but i dont have much room due to the ic piping. Im looking at running 18-20psi boost so does anyone know if the 25mm dv fittings are a good start? Also can i just put a filter on the dv fitting or is it better to have one either side of the maf and use the main filter?
