Title: Strange Boost
Post by: Alexis on August 21, 2014, 08:01:26 am

Hello All,

I seem to have encountered an odd problem with my boost.  I have lost all boost in 1st & 2nd year (only boosting to around 4psi) but then I get the full 12psi through 3rd to 6th and it pulls as normal.

Can anybody shed any light on this or advise me on what to check?

Thanks in advance  :happy2:

Diverter Valve?

That wouldn't explain how it's not working in only some gears though.

With the right tools it's an hours work so it could be worth crossing off the list.

Yeah I was thinking of taking it off and inspecting it. 

I changed a mate's a while back and I have a spare one in the shed and like you said it's looking like a trial & error job.

Thanks again  :happy2:
