Am I wrong? I thought it > indicates overboost which you should have adjusted. Well, no, I don't think you are wrong. The manual for the C900 says it should not enter the red, but may under certain circumstances. It does say to have the APC system checked if it does repeatedly enter the red. My C900 is setup to go all the way to the red (rather than about 3/4 the way up the yellow), but snap back into the yellow if it does enter the red. Extreme APC "tuners" (if that's what we can call them) just screw the APC all the way for top red-zone boosting. Pulling the 'C' hose off the APC solenoid does the same thing - turbo is then only controlled by the foot, rather than an OEM computer. BTW, to me, "overboost" means when the fuel pump shuts off violently because it can't feed the turbo pressure. Scary and dangerous. Since I don't actually know what the 9-5 *should* do, I was making suggestions according to the other turbos I've driven. The 9-5 I drove was not as responsive as the 900 turbos I've owned and didn't really get the chance to test it to full boost, what with the salesman sitting in the passenger seat :) I don't think it should enter the red and I don't think the boost should fall off so rapidly. I'm sure Gary's car is not setup right. It's only when he mentioned the behaviour of the gauge that I fully understood what he was experiencing. If it's been tinkered with like that (I shudder to think about whether knock-sensing has been disabled), it should be setup correctly as soon as possible to prevent any permanent damage. >> I think you need to get it back to the dealer or to a mechanic who knows how >> to setup turbochargers correctly.

I just missed out on a 1994 9000 CSE in black a couple of months ago with full leather interior, walnut dash, asymmetrical Aero wheels, brand new tyres all round, full history and only about 40,000 miles on the clock. It was a steal as well at 2250 UKP. I just didn't say "yes, I'll buy it" quick enough :( Paul 1985 900i 16V 1989 900 Turbo S http://pjgh.go.dyndns.org/saab/index.html
