I"m asking this for someone i know who spent a year or 2 doing a nice installation of an ALH TDI into a Pinzgauser. He's trying to get more performance out it- chip, bigger nozzles etc. I told him he should get an EGT gauge. He went ahead and installed ,putting the probe i believe where the EGR pipe used to come out. Going up big hills under throttle he's only seeing 800 o max. Is it possible the probe is too far downstream, or is it because the ECU driven fuel management keeps the exhaust temps low ?
