Great thread so far - I'm happy I seem to have gone down the right path. 3" exhaust, dp chip and scan gauge. Dual pillar VDO egt and boost gauges.
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.
