Will try that, thanks for the help.

Yes have the needle valve in the mods. Just trying to improve my fuel economy as it seems to have increased since the mods. Its running 17psi boost on my gauge. Cheers

Hi Guys New to the forum and have just done the NADS with Dawes valve to me GU3 04 ZD30 wagon as describe on this thread and has made a remarkable improvement on EGR temps and boost spiking. The Patrol had a DP Chip fitted and was wondering if i need to remove the chip now i have fitted the Dawes valve etc and maybe help with fuel efficiency? Also done the EGR block with gauges, HPD intercooler & fan with catch can. Cheers
