Just installed my pyro and boost gauge into my 2000 3 litre patrol as i'm getting ready to install the dawes system, took the old girl for a spin and i'm a no brainer to these things!,have to say ive also installed a brand new straight through 3 inch exhaust not cat or muffler, when I hit a slight hill the EG climbed to just over 500 degrees, when cruising at 100kph sits around 300 is this normal? also the boost gauge is all over the show, gauge is a Speco boost gauge, boost gets to around 9psi then all of a sudden drops to 0 under accleration, then spikes to 15 then just drops again, its like its loosing vacuum, I did notice the intercooler is showing a small sign of oil weep? when cruising the boost sits at around 5psi then just drops again,then comes back to life and shoots up to anything to 10-15psi its like the needle has a mind of its own, can anyone offer some advise please as to what could be causing these weird things with the boost gauge, oh and its a brand spanking new gauge
