Boost was still all over the place though. Jumping to 20 psi, then dropping to 10 then building back up to 15-16 psi - all while maintaining the same speed on a flat.
Fitted one of mudski's dawes/needle kits over the weekend and it stopped the erratic boost issues I was experiencing. Car is much nicer to drive with a smooth boost curve.
I used the instructions in mudski's kit and had everything up and running in a couple hours - car sits nicely on about 15-16psi at full boost and on 10psi at 100k's.
EGT's stay around 200-250 around town and only hit 400 when I'm right up it and drop again pretty quick.
I had my exhaust fitted by Berrima diesel and I see they cut the original heat shield in half to fit in the new dump pipe - worked out ok 'cause I had to get the egt probe fitted at a later date.
Interested to hear if anyone has tried any additional heat shielding - I heard sometimes the heat under the bonnets of gu's sometimes kill the aux battery - so far so good though.
Its good to see my jibberish is understood by fellow Patrollers. Thanks.
Why did BD cut the heat shield though? Its not that hard to remove, and the shield still can be used on any aftermarket zorst. I would have been quite annoyed if they did that to my car.
As for additional heat shielding. The heater wrap stuff is pretty effective on the dump pipe. I use this on mine, works really well. You just need to wear gloves when wrapping it on. Otherwise you will have some itchy hands for a while.
