Re: No boost

if you disconect wastgate hose from apc, and take for a spin, do you get full boost, (dont hammer it as it will go to cut off, if it does suspect apc, check fuse and wiring)

any mis firing lately, coule be plug problem, also try re-setting ecu, by disconecting battery leads for half an hour, and doing an adaptation run.

hope this helps

Re: No boost

Try double checking the vacuum pipe from the dump valve, I've been having problems getting full boost lately and my pipe is perished, although looks alright at first glance. The car was only boosting half way into the yellow.
