Boost problem

I am having a boost problem. I have an autometer ultralite boost gauge which, at idle is showing around -18 (in.hg) and when accelerating hard only goes up to around 5 psi. I have an aftermarket ECU and boost jets fitted and normally would get to around 12psi. When driving normally the gauge used to sit around the 0 mark but now is around -10.

 

I have checked to see if any pipes have come off, but can't see anything obvious. I also only use Optimax, so I don't think detonation should be a problem or I am in safety mode. :confused:

 

Any ideas or help would be appreciated.

 

Cheers

 

Jeremy

    You may be in safety mode, run a diagnostic to see if there is a cause, other folk will give you more ideas soon.
