I think the damp roads were assisting in keeping boost down, but most of the time I never got through 2nd before backing off. Once I did tramp on it at about 90kmh - it kicked back to 2nd and just started fishtailing, then changed into 3rd and kept going. I got off the gas pretty fast after that - but that was damp road too. It felt pretty good. It's given me the taste of real grunt and now that the car is out of warranty ..................

I drove the whole time with the radio and the air con switched off. No pinging at all. When it died on me on Saturday I must have popped the max boost trigger in the ECU. I dunno what pressure that is - searching in the archives here I think 9 or maybe 12 psi ???? That was the only time it must have peaked at way above normal. Most of the Easter weekend was wet or damp, and with the spooling sound so loud I was only stomping on it for a few seconds, getting wheel spin and backing off. I hope no damage done

OK ratter, You win - first reply! Finally the guys in the worshop found their mistake today and plugged the actuator hose back in. That's why it was boosting off the scale. That's why the spooling was noisier. All fixed. My old T is back. Thanks guys.

Well, no boost checking for me now. The engine went into limp mode (I think) on the way back from shops this morning when I picking up the tee piece and some silicone hose. Gave it a little squirt in 1st, started spooling up, then there was a popping noise and power was gone. It ran like a ragged dog on 3 or 4 cyl for a minute or so till I found somewhere to pull over. I switched it off, rang the workshop telling them something very serious was definitely happening, then after ~10 minutes, restarted it and it is running fine again. I have been for a short drive since and the turbo is still spinning up, but I'm not going to drive it any more except to the workshop on Monday morning. Over boost I'm guessing. Hopefully they'll get to the bottom of it and I'll get my old T back.

OK Guys, Supercheap cheapest - $69 I rumbled through my stuff and have a 3" 0-100psi gauge that should do, plus some lengths of hose and tube and fittings. Next dumb question - Where is the easiest place to temporarily tap into pressure? I've had a look around under the bonnet and there are no obvious spots jumping out at me.

Yes, I will take this sensible advice.

If that was the case, it's been seriously ill since new. The grunt it has now is verging on silly (for a gentleman driver such as myself). It starts whistling on 1/4 throttle and if the road is damp I have to be somewhat cautious when giving it a squirt. If the surface is dry, I'm starting to go sideways giving it a squirt during a gentle curve. The traction control doesn't seem to be dealing with it well and it's going sideways already before the T/C light comes on. I've booked it back at the shop to get the waste gate actuator checked out once and for good.

Huh! Connecting one wire! Those engine tuning companies must be making a killing! ZF auto. I had it tramping in 2nd today.

I got it back from them tonight after they checked and rechecked. It still goes like a rocket! It has never felt as quick - not even in the first month after picking it up. It's a company car and consequently, I've never bothered finding out exactly how boost is regulated or where all the little hoses go! I see how that all works now. Potentially very nasty - but there is no pinging and it is running smooth as so far. The workshop checked it over today.

I thought I would loose boost with a leaky hose? Whatever. Damn! It sure feels good. I suppose melted pistons or a blown engine will be the eventual result it is left as is It's back in the workshop now getting checked - I knew it was too good to be true.
