If so what spring are you using, fitted my DV when it was standard and worked a dream. Now it's running stage one ( 1.5 bar ) and I can swear its leaking mid throttle as the engine pick up and response seems to be dead at mid throttle. Comes with yellow as standard and I've tried a blue but then it barely dumps at all, at the moment I've settled for yellow + one washer but hasn't seemed to cure the fault.
Well yes I've spoke to Forge and they're saying the same thing but to take that as a guide only as every vehicle is different and one spring may not be the same for another despite similar boost pressures.
Hi Ben, I have the same forge dv with the yellow spring and RST stage 1, and don't have any issues so far. /Vic
Haven't a clue, it's more controlled by the boost supplied on the back of the diaphragm to hold it shut, the spring itself just assists on partial throttle when there's a pressure difference.
Im on stg2 with yellow, on throttle it hits 19 psi and them start falling to 17. Should y upgrade to blue spring?
19 psi seems a little low for a stage two. I usually work in bar and my stage one map records around 1.5 bar ( 21psi? ).
